Valeria uses the smoothie store's loyal customer app, and she's earned a reward worth $2 off her next purchase. Knowing she goes there often, her grandma clipped a "Save 15%" coupon" from the newspaper and gave it to Valeria. If her smoothie purchase is $7.50 and the store will only let her use one discount, which should she choose to lower the cost most?

Valeria should use the reward worth $2 off her next purchase.

Step-by-step explanation:

To find the answer, you have to determine what Valeria would pay with each discount:

-reward worth $2 off her next purchase:

$7.50-$2=$5.50

-Save 15% coupon:

$7.50*0.15=$1.125

$7.50-$1.125=$6.375

According to this, the answer is that Valeria should use the reward worth $2 off her next purchase as she will pay $5.50 and with the save 15% coupon she would have to pay $6.375.
