Question 5 • Math 7 B (M12 25/26 S2)

Lou’s Shoes is having its annual Flag Day Sale and is offering a 25% discount on all regularly priced shoes. Kayla spends $13.50 buying sandals and sneakers. Determine which equation represents how much Kayla will spend on sandals after the discount.

Answer
A
$13.50 = 0.75(x + 10)
B
$13.50 – 10 = 0.75x
C
$13.50 + 10 = 0.75x
D
$13.50 = 0.25(x + 10)

Explanation

A 25% discount means Kayla pays 75% of the regular price, so the sale price is 0.75 times the regular price. If sandals cost x dollars regularly and sneakers cost $10 regularly, their combined sale price is 0.75(x + 10). Since Kayla spends $13.50 total, the equation is $13.50 = 0.75(x + 10), choice A.
