3. at a store andre paid $15 for each t - shirt he bought plus he used a coupon for $10 off his purchase. if andre paid $80 after he used the coupon, how many t - shirts did he buy?

Answer

Explanation:

Step1: Add the coupon - value back

First, find the total cost before the coupon. Since he got $10 off and paid $80 after using the coupon, the total cost before the coupon was $80 + 10=90$. $80 + 10=90$

Step2: Calculate the number of t - shirts

Each t - shirt costs $15. To find the number of t - shirts, divide the total cost before the coupon by the cost per t - shirt. $\frac{90}{15}=6$

Answer:

6
