Asked by Patrick
1. Quinn spent $16.49 for 3 magazines and 4 sheets of stickers. The magazines cost $3.99 each and the sales tax was $1.02. Quinn also used a coupon for $1.50 off her purchase. If each sheet of stickers had the same cost, how much did each sheet of stickers cost?
2. Jairo spent $40.18 on 3 music cds. Each cd cost the same amount. The sales tax was $2.33. Jairo also used a coupon for $1.00 off his purchase. How much did each cd cost?
I have tried solving the above problems several different ways and cannot figure out how. Can you please help me.

1.
cost of sticker ---- x
3(3.99) + 4x + 1.02 - 1.50 = 16.49
11.97 + 4x - .48 = 16.49
4x = 16.49 - 11.97 + .48
4x = 5.00
x = 1.25
#2 is just as easy, just follow my steps
let the cost of each CD be x

Can you just take $40.18/3 to find out the cost of each cd?

No, you can't Patrick, because there was also sales tax and a coupon. You therefore must subtract the sales tax and add the coupon value, then divide that number by three.

You'd actually subtract the sales tax AND the coupon. Then divide by 3
