four friends use an online coupon to get a $15 discount on each concert ticket they buy. they spent $312 for the four tickets. what was the price of one ticket without the discount.

Answer 1

Let t be the ticket price.

Let d be the discount.

4(t-d)= total price

4(t-15) = 312

t-15 = 78

t = 78 + 15 = $93
