Answer:
3s - 10 = 65
Explanation:
s = the shirt price
Since Jason bought 3 shirts, we need to multiply the 3 shirts by its value which would be 3s. He has a coupon for $10 off, so we need to subtract 3s by 10. Since he spent $65 we need to set the whole equation equal to 65 and out final answer would be 3s - 10 = 65.
