Answer:
the answer is $8.29
Step-by-step explanation:
1.60 marked up by 60% in decimal form is .60
multiply that .60 by 1.60 and you get .64
you add .64 to 1.60 and you get 2.56
you multiply 2.56 by 3 and you get 7.68
you have a 8% sales tax so you multiply 0.08 by 7.68
you will get .61 you add that to 7.68 to get $8.29
Answer:
$6.64
Step-by-step explanation:
When the price of an item is marked up by a percentage, the new price (after markup) is result when the product of the percentage and the original price added to the original price.
The price after markdown is similar to the mark up except that the product of the percentage and the original price is subtracted from the original price.
Hence when a box of spaghetti at the grocery store is purchased for $1.60 wholesale and is marked up by 60 percent, the new price
=60% * $1.60 + $1.60
$2.56
If the store marks down the item by 20 percent, then the new price becomes
= $2.56 - 20% * $2.56
= $2.048
If a customer wants to buy 3, the price
= $2.048 * 3
= $6.144
Including 8% tax, the price becomes
=$6.144 + 8% * $6.144
= $6.63552
To the nearest cent
= $6.64

Pack B has 24 cookies for $4.10. Which pack has cheaper cookies? Anita is offered two summer jobs. One is in retail and pays $500 for a 40-hour work week. The other job is at a restaurant and pays $12 an hour. Which job has a higher hourly rate?
Answer:
van : 12 miles per gallon
cabinets: 3 cabinets a day
retail job for $500
Step-by-step explanation:
van: 240 miles/20 gallons = 12 miles per gallon
cabinets: 24/8= 3
jobs: $500 for 40 hours and $12 times 40 hours gets you $480
first job pays $20 bucks more
Ques 1)
A van travels 240 miles on 20 gallons of gas.
This means that 20 gallons of gas is used to travel 240 miles.
This means that:
1 gallon of gas is used to travel :
[tex]\dfrac{240}{20}=12\ miles[/tex]
Hence, it travels 12 miles per gallon.
Ques 2)
Carlos installed 24 wooden cabinets in 8 days.
i.e. in 8 days he install 24 cabinets
This means in 1 day he will install
[tex]\dfrac{24}{8}=3\ cabinets[/tex]
On the average, he will install 3 cabinets each day.
Ques 3)
100 sheets cost $ 2.50
This means that cost of 1 sheet is: $ 0.0250
( since, [tex]\dfrac{2.50}{100}=0.0250[/tex] )
150 sheets at $3.50
This means that cost of 1 sheet is: $ 0.0233
( since, [tex]\dfrac{3.50}{150}=0.02333[/tex] )
This means that the cost per sheet is cheaper in the buy:
150 sheets at $3.50.
Ques 4)
Pack A has 36 cookies for $5.90.
This means that cost of 1 cookie is: $ 0.16388 )
( since, [tex]\dfrac{5.90}{36}=0.16388[/tex] )
and Pack B has 24 cookies for $4.10.
This means that cost of 1 cookie is: $ 0.170833
( since, [tex]\dfrac{4.10}{24}=0.170833[/tex] )
The cost per cookie is cheaper in Pack A.
Hence, the pack which has cheaper cookies is: Pack A.
Ques 5)
One is in retail and pays $500 for a 40-hour work week.
This means that the payment for 1 hour is: $ 12.5
( since, [tex]\dfrac{500}{40}=12.5[/tex] )
The other job is at a restaurant and pays $12 an hour.
This means that the job which has a higher hourly rate is:
In retail which pays $500 for a 40-hour work week.
( since 12.5>12 )

Answer: 81 in. (6.75 ft.) by 60 in. (5 ft.)
First, convert 27 ft. and 20 ft. to inches to make it easier to work with. This would convert like this:
27 ft. x 12 in. = 324 in.
20 ft. x 12 in. = 240 in.
This also means that the scale converts to 1/4 in. = 12 in.
Now, take your 324 in. and 240 in. and apply them to the scale.
For every 12 in. (1 ft.) in the non-scale room dimensions, there will be one 1/4 in. on the scale. That would apply like this:
324 in. (27 ft.) x
1/4 in. =81 in. [or 6.75 ft.]
240 in. (20 ft.) x
1/4 in. = 60 in. [or 5 ft.]

Hector went shopping for a computer. At RST store, a computer originally prices at $955 had a price reduction of 40%. What was the reduced price?
x 40
------ = --------
955 100
Cross multiply
955x40=38200
38200÷100=382
u get 382
955 -382= 573
$573
So here are the rules with change by percentage (m = percentage in decimal form, n = original, and r = new):
If increase: (1 + m)n = rIf decrease: (1 - m)n = rSince this is a price reduction, we will be following the second rule. In this case:
[tex]40\%=0.4\\\\(1-0.4)*955=r\\0.6*955=r\\573=r[/tex]

Raizon is 80 flyers per hour
Step-by-step explanation:
In essence (if you see what I did there) a unit rate (strictly in this context) is how much work is done for 1 hour of time. To find this, we simply divide the number of flyers by the number of hours of worked.
So, for Essence:
[tex]\frac{420}{3} = 140[/tex]
The units for this problem will be flyers per hour. So, Essence has a unit rate of 140 flyers per hour.

distibutive property
Answer:
Everything should simplify down to -9a-3 (your answer)
Step-by-step explanation:
Distributive property is basically multiplying the outside number into the inside parenthesis (). Basically #(a)--->#a or #(a+b)---> #a+#b
Since you're not ask to solve for anything but simplify, just multiply 3 to -3a and -1.....
so 3*-3a is -9a and 3*-1 is -3 and you have 3(-3a-1)= -9a-3
Final answer:
The distributive property is a mathematical property that allows us to distribute multiplication over addition or subtraction. It helps simplify expressions and perform calculations more efficiently in algebra and arithmetic.
Explanation:
The distributive property is a mathematical property that allows us to distribute multiplication over addition or subtraction. It states that for any numbers a, b, and c, the expression a * (b + c) is equal to a * b + a * c. This property helps us simplify expressions and perform calculations more efficiently.
For example, if we have the expression 3 * (2 + x), we can use the distributive property to simplify it to 3 * 2 + 3 * x, which becomes 6 + 3x. This allows us to break down the calculations into smaller steps and avoid errors.
The distributive property is one of the fundamental properties of multiplication and is widely used in algebra and arithmetic.
A pizza delivery worker purchased a used motor scooter that had been driven 12,100 miles. He drives the motor scooter only on days he is working, during which he drives an average of 50 miles per day. After d days of pizza delivery, the motor scooter has been driven a total of 25,000 miles. Which of the following equations best models this situation?
Final answer:
The equation that best models the situation of the pizza delivery worker's scooter mileage is 50d = 12,900, where d represents the number of days worked.
Explanation:
The question asks us to find out which equation best models the situation where a pizza delivery worker drives a certain number of miles after d days of pizza delivery. To start, the worker bought a scooter with 12,100 miles on it. Each day of work he adds 50 miles to the total. After d days of delivery, the total miles driven on the scooter equals 25,000. We are looking for an equation that represents this scenario.
The total mileage on the motor scooter after d days can be calculated by the initial mileage plus the product of the number of days and the average miles driven per day. Mathematically, this is represented by:
12,100 miles + 50 miles/day × d days = 25,000 miles
To find the equation that models this situation, we subtract 12,100 from both sides to isolate the term with d on one side:
50d = 25,000 - 12,100
So, the equation that models this situation is:
50d = 12,900
