Question

Marty ordered three extremely accurate and scientific water-balloon launchers from a mail order catalog (one for himself and two for his friends). The total price including shipping charges was $50. If the total shipping cost was $5, how much did each launcher cost?

Answer 1

3 launchers + shipping = $50
shipping = $5
so to find the price of just the launchers we do $50-$5=$45
so 3 ballons = $45
divide be 3 to find the price of one launcher $50 / 3 = $15
