Final answer:
To get $10 in coupons at The Green House of Salad, where a $1 coupon is awarded for every 3 salads bought, one must purchase at least 30 salads.
Step-by-step explanation:
The question involves determining the least number of salads one must buy to accumulate $10 in coupons at The Green House of Salad, where you receive a $1 coupon for every 3 salads purchased. To find the answer, we can set up the following equation:
Number of coupons = Total number of salads bought / 3
Since each coupon is worth $1, the student wants to accumulate $10 in coupons, which means they need 10 coupons. Using the equation and solving for the total number of salads:
10 coupons = Total number of salads bought / 3
Total number of salads bought = 10 coupons * 3
Total number of salads bought = 30
Therefore, the student must buy at least 30 salads to get $10 in coupons.
