Question: Dillon wants to buy a model airplane that costs $34.00. She has a $5.00 bill and a 75% off coupon. How much more money does Dillon need to get the model airplane?
When you're ready, check below for the solution.
Solution: Since the coupon is for 75% off, the model airplane costs 25% of its original cost, which is half of a half of $34.00. Half of $34.00 is $17.00, and half of that is $8.50. If Dillon has $5.00, she needs $8.50 – $5.00 = $3.50 more to buy the model airplane.

Rather than have the kids “tune out” with electronics, have them “turn on” their brains with math games!
