Without the coupon, 6 shirts would cost (6 x 9) = $54 .

The coupon saved you $5 off of your purchase (not off of each shirt),
so you got the whole batch for (54 - 5) = $49 .
first, multiply the cost of each shirt by how many shirts bought. The answer would be 54. So next you would subtract the 5 dollar discount from the total cost of the shirts. 54-5= 49
