Answer:
$68.25
Step-by-step explanation:
1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.
2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.
Therefore, the cost of 3 sweatshirts is $68.25.
Mentally your dividing the 12.50 by 10 and then thats 1/10 of it.
<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
