Question

Laced Up shoe store had its annual spring sale, where customers pay full price for one pair of shoes and half of the full price for a second, less-expensive pair. During the sale, Eduardo purchased a pair of dress shoes at full price and a pair of sandals at half price. The dress shoes cost $54, and Eduardo paid $63 in all. What was the cost of the same pair of sandals at full price?

Answer 1

By subtracting the full price of the dress shoes from the total amount paid and then doubling the remaining amount, we determine that the full price of the sandals was $18.

Step-by-step explanation:

The student is asking about a sale at Laced Up shoe store where the customer pays full price for one pair of shoes and half price for the second pair if it's less expensive.

Eduardo bought a pair of dress shoes for $54 and paid $63 total, which includes the half-priced sandals.

To find the full price of the sandals, we subtract the full price of the dress shoes from the total paid:
$63 - $54 = $9

Since the sandals were half price, we double the price paid to find the full price:
2 × $9 = $18

Therefore, the cost of the sandals at full price was $18.
