Money math skills are some of the most important, most often used math skills in everyday life. Even kids who may not do much purchasing on a regular basis will benefit from improving their money math skills. This week’s word problem challenge will help kids practice division, subtraction, percents and other elementary school math. Give it a try, practice a little every day, and your skills will soar! **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.
