A business owner pays $1,200 per month in rent and a total of $120 per hour in employee salary for each hour the store is open. On average, the store brings in $200 in net sales per hour. Which equation can be solved to determine the break-even point if x represents the number of hours per month the store is open?
The break-even point can be determined by setting the net sales per hour equal to the total cost per hour. The equation to solve for the break-even point is $200x = $1,320x. By dividing both sides of the equation by $1,320, we can find the value of x, which represents the number of hours per month the store needs to be open to break even.
Explanation:To determine the break-even point, we need to find the number of hours per month the store needs to be open in order to cover all its costs. The total cost for each hour the store is open is the sum of the rent and the employee salary. So, the total cost per hour is $1,200 + $120 = $1,320. The break-even point is reached when the net sales per hour equals the total cost per hour:
Net sales per hour = Total cost per hour
In this case, the net sales per hour is $200, so we can set up the equation:
$200x = $1,320x
where x represents the number of hours per month the store is open. By dividing both sides of the equation by $1,320, we can solve for x:
$200 = $1,320x / $1,320
$200 / $1,320 = x
x = 0.1515...
So, the break-even point is approximately 0.1515... hours per month, or about 9.09 minutes per month.
Eddie is reading a novel for English lass. He has read 173 out of 480. About what percent of the book he has read ?
Final answer:
Eddie has read about 36% of the book for his English class, calculated by dividing the number of pages read by the total number of pages and then multiplying by 100.
Explanation:
To determine what percent of the novel Eddie has read for his English class, you would use the formula for calculating percentage: Percentage = (Part / Total) × 100. In this case, the part is the number of pages Eddie has read (173 pages) and the total is the number of pages in the novel (480 pages).
Now, let's calculate the percentage:
Percentage = (173 / 480) × 100
First, divide 173 by 480, which gives approximately 0.3604. Then, multiply this result by 100 to convert it into a percentage.
Percentage = 0.3604 × 100 => 36.04%
Therefore, Eddie has read about 36% of the book for his English class.

At 9:00 am linda leave work on a trip, sets her cruise control at 60mph. At 9:30 am, Bruce notices she left her briefcase and gets on the free way driving 90mph. At what time will Bruce catch up with Linda?
Bruce will catch up with Linda at 9:48 am.
Explanation:To find the time at which Bruce catches up with Linda, we need to determine the time it takes for Bruce to cover the same distance that Linda has already covered.
Since Linda starts her trip at 9:00 am and Bruce starts 30 minutes later at 9:30 am, Linda has a head start of 30 minutes or 0.5 hours.
In that 0.5 hours, Linda travels a distance of:
Distance traveled by Linda = Speed * Time
Distance traveled by Linda = 60 mph * 0.5 hours
Distance traveled by Linda = 30 miles
Now, Bruce needs to catch up with that distance of 30 miles. Let's find the time it takes for Bruce to cover that distance at his speed of 90 mph:
Time taken by Bruce = Distance / Speed
Time taken by Bruce = 30 miles / 90 mph
Time taken by Bruce = 0.33 hours
Since Bruce started at 9:30 am, he will catch up with Linda at:
Catch up time = Start time + Time taken by Bruce
Catch up time = 9:30 am + 0.33 hours
Catch up time = 9:48 am

If a photo measuring 4 inches by 6 inches is placed in a photo frame that is 2 inches wide all around, what percent of the framed photo is the photo itself?
Answer:
Percentage of the photo = 50%
Step-by-step explanation:
Given that the measurement of the photo is 4 inches by 6 inches and the measurement of the photo frame is 2 inches wide all around, it simply implies that is measurement of the photo frame is (4inches + 2inches) by (6 inches + 2inches). I.e 6inches by 8inches
To find the percentage of the photo itself, let find the area of the photo and that of the frame
Area of photo = 4 inches x 6 inches = 24inches²
Area of photo = 6 inches x 8 inches = 48inches²
Percentage of the photo = area covered by the photo / area covered by the frame x100
Percentage of the photo = 24/48 * 100
Percentage of the photo = 50%

Kiki wants to rent a bounce house for her daughter's party. The cost, y, to rent a bounce house for a number of hours, x, is shown in the table. The initial set-up fee is included in the cost.
Answer:
The initial setup fee is $55.The hourly rate is $65.Step-by-step explanation:
First of all, we need to find the equation that models this situation.
Let's find the constant ratio of change using two pair of values from the given table.
[tex]m=\frac{575-185}{8-2}=\frac{390}{6}=65[/tex]
The ratio of change is 65.
In other words, the hourly rate is $65, that is, 65 dollars per hour.
Then, we use the point-slope form to find the equation
[tex]y-y_{1} =m(x-x_{1} )\\y-185=65(x-2)\\y=65x-130+185\\y=65x+55[/tex]
Where [tex]55[/tex] refers to the initial condition.
In other words, the initial setup fee is $55.

Let us take hours worked as x and Amount paid as y.
In the given functions
y = 15.4x ...(1)
y = 15.2x ...(2)
y = 16.4x ...(3)
y = 14.9x....(4)
We need to check which satisfies the relationship between x and y.
If x=2 then we need to get 30.4
So let us put x=2 in equation 1.
y=15.4×2
=30.8
Which does not matches.
Now let us check with second function.
y=15.2×2
y=30.4
It matches.
So let us check for other values.
x=4
y=15.2×4
y=60.8

the walls of a square room need painting.Each of the four walls is 12 ft wide by 8.5 feet tall.One gallon of paint covers 75 ft.How many gallons will you need?
The walls of a room need painting. Each of the four walls is 12 ft wide by 8.5 feet tall.
We know that, Area = length [tex]\times[/tex] width.
So, the area of one wall = 8.5 ft [tex]\times[/tex] 12 ft = 102 square feet
Thus, the area of 4 walls = 4 [tex]\times[/tex] 102 = 408 square feet
One gallon of paint covers 75 square feet. We need to find how many gallons of paint will cover 408 square feet.
So, the amount of gallons of paint needed = 408[tex]\div[/tex]75
= 5.44 gallons
So, 5.44 gallons are needed to cover 408 square feet.
To find the number of gallons of paint needed to paint the walls of a square room, calculate the total area of all four walls and divide it by the coverage of one gallon of paint.
Explanation:To find the total area of all four walls, we need to calculate the area of one wall and then multiply it by four. The area of one wall is the product of its width and height, which is 12 ft x 8.5 ft = 102 ft².
So, the total area of all four walls is 102 ft² x 4 = 408 ft².
Since one gallon of paint covers 75 ft², we divide the total area of all four walls (408 ft²) by the coverage of one gallon of paint (75 ft²) to find the number of gallons needed: 408 ft² ÷ 75 ft² = 5.44 gallons.
Therefore, you will need approximately 5.44 gallons of paint to paint the walls of the square room.
Write an expression for the perimeter of the triangle shown below: (4 points)
A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.
6.9x − 16
6.9x + 16
0.1x − 16
0.1x + 16
Answer:
The correct option is 3.
Step-by-step explanation:
It is given that the length of sides of a triangle are 0.5x+9, 3x, and -3.4x-25.
Let a=0.5x+9, b=3x, and c=-3.4x-25.
Perimeter of a triangle is the sum of length of all three sides.
[tex]Perimeter=a+b+c[/tex]
Substitute a=0.5x+9, b=3x, and c=-3.4x-25 in the above equation.
[tex]Perimeter=(0.5x+9)+(3x)+(-3.4x-25)[/tex]
On simplification, we get
[tex]Perimeter=0.5x+9+3x-3.4x-25[/tex]
Combine like terms.
[tex]Perimeter=(0.5x+3x-3.4x)+(9-25)[/tex]
[tex]Perimeter=(0.1x)+(-16)[/tex]
[tex]Perimeter=0.1x-16[/tex]
Perimeter of the triangle is 0.1x-16. Therefore the correct option is 3.
