Rebecca gave the cashier $20 to pay for 3 tickets to a museum. The cashier gave her back $1.28 back in change. Each ticket cost the same amount. How much did each ticket cost?
Take 20 and subtract 1.28. That gives you 18.72 which is how much it cost for all 3 tickets. Then divide the 18.72 by 3 and you get 6.24. So it costs 6.24 for each ticket. Hope that helps.
