Final answer:
The discount does Olivia receive on the new Apple Watch with her coupon is B) 15% as her coupon offers a 15% discount off the full price of the Apple Watch.
Step-by-step explanation:
Olivia has a coupon to purchase a new Apple Watch, which provides a 15% discount. To determine the discount percent, we look at the options provided. Since the coupon specifically states a discount of 15%, this is the amount that will be subtracted from the total cost of the Apple Watch. Therefore, the correct answer to the question is 'B) 15%'.
A discount is a reduction in the regular price of an item. In this case, a coupon that offers a 15% discount means that Olivia will pay 85% of the full price (since 100% - 15% equals 85%). This concept is a basic percentage calculation in mathematics often covered at the middle school level. Discounts are a practical application of percentages, which are a fundamental part of financial literacy and consumer math.
