Answer:
Looks right to me! Great work!
I believe the price for one box with the coupon will be $3.15. This is because 4.50 * .30 = 1.35
4.50 - 1.35 = 3.15 Thus the discounted price will be $3.15
let the short side = x
Long side = 3x
Middle side = 3x -3
x + 3x + 3x -3 = 32
Simplify:
7x -3 = 32
Add 3 to both sides:
7x = 25
Divide both sides by 7:
X = 5
answer: shortest side = 5cm
