A clothing store is running a special in which customers receive a free pair of jeans with the purchase of 4 shirts. It costs the clothing company $3.46 to produce one shirt and $5.56 to produce one pair of jeans. The store is selling each shirt for $21.46. Approximately how much money will the company make if 42 customers take advantage of the special?
The clothing company will make approximately $214.60 if 42 customers take advantage of the special.
Explanation:To calculate the amount of money the company will make, we need to determine the total cost of shirts and jeans given out for free.
Each customer will receive a free pair of jeans for every 4 shirts purchased.
The cost of 1 shirt is $3.46 and the cost of 1 pair of jeans is $5.56.
So, the cost of 4 shirts is 4 x $3.46 = $13.84.
Therefore, for each set of 4 shirts, the company is losing $13.84 on production costs and gaining $21.46 on sales.
For 42 customers, the company will distribute 10 sets of 4 shirts and give away 10 pairs of jeans.
The total amount of money the company will make is (10 x $21.46) = $214.60.
I don't know what the symbol means or what to do.
Answer:
Step-by-step explanation:
That weird symbol means "element". In our case, the elements of the domain (the x-values) are -15, -6, -1. Which tells us that we are going to sub each one of the numbers into the equation and solve it for the corresponding y value. That in turn gives us the coordinate point. The equation is
x + y = 6
Subbing in first -15 for x:
-15 + y = 6 and
y = 6 + 15 so
y = 21 and the coordinate point is (-15, 21).
Subbing in -6 for x:
-6 + y = 6 and
y = 6 + 6 so
y = 12 and the coordinate point is (-6, 12).
Subbing in -1 for x:
-1 + y = 6 and
y = 6 + 1 so
y = 7 and the coordinate point is (-1, 7)
The second choice is the one you want.
Just remember that x is the domain and any elements in the domain go in for x.
Also remember that y is the range and any elements in the range go in for y

What is the perimeter of trapezoid JKLM?
+ units
2 + + units
9 + units
9 + + units
answer is D
Perimeter is the sum of the length of the sides used to make the given figure. The correct option is D.
What is the perimeter?Perimeter is the sum of the length of the sides used to make the given figure.
The length of the different sides of the trapezoid can be written as,
JK = 3 units
KL = √(2² + 1²) = √5 units
LM = 6 units
JM = √(1² + 1²) = √2 units
Now, the perimeter of the trapezoid JKLM is,
Perimeter JKLM = 3 + √5 + 6 + √2 = (9 + √5 + √2) units
Hence, the perimeter of the trapezoid JKLM is (9 + √5 + √2) units.

Factor the expression. 3r2 – 75
(3r –5)(r + 5)
(3r +5)(r – 5)
3(r – 5)(r + 5)
3(r – 5)(r – 5)
factor 3r^2-75
you would move the 3 to the outside of the parenthesis
then you have 5*5 = 25 and multiply that by the 3 to get the 75
