Answer:
$68.
Explanation:
The formula for calculating a discount is:
Sale price = Original price - (Original price * Discount%)
In this case, the original price is $80 and the discount is 15%. So, the sale price is:
Sale price = 80 - (80 * 0.15)
Sale price = 80 - 12
Sale price = $68
Therefore, the sale price of the shoes is $68.
