Solving Word Problems

​Tomorrow, you have your first test.

​To prepare, we will look at how you can solve word problems. Make sure to read each problem carefully. Then, make a plan to solve.

​Example:

​Mr. Tyler had $40 to buy shoes for his children. He bought 2 pair of shoes for his daughter that were $5.60 each. Then, he bought three pairs of shoes for his son that were $4.65 each. How much money did Mr. Tyler have left after his purchases?

Start with the question to idenitfy the needed operation(s).

​

​How much money did Mr. Tyler have left after his purchases?

​This means you will SUBTRACT the cost of shoes from the amount Mr. Tyler started with.

​2 pairs for 5.60 each = 11.20

​3 pairs for 4.65 each = 13.95

​11.20 + 13.95 = 25.15

​40-25.15 = 14.85 remaning
