Plan for Problem Solving 0-1 Plan for Problem Solving

Four-step problem-solving plan Understand the Problem (Read the problem and directions carefully) a. Identify what information is given. b. Identify what you need to find. Plan the solution (choose a variable to represent the unknown, and write an equation.) Solve the problem. Check the solution. a. Does your answer make sense? b. Does you answer fit the information in the problem?

Example 1 pg. P5 Use the four-step plan LAWNS: Mr. Nunez’s lawn is 50 feet long and 35 feet wide. He paid a lawn service $350 to aerate and reseed his lawn. What did the lawn service charge per square foot?

Example 1 pg. P5 Use the four-step plan LAWNS: Mr. Nunez’s lawn is 50 feet long and 35 feet wide. He paid a lawn service $350 to aerate and reseed his lawn. What did the lawn service charge per square foot? $0.20 per square foot

Example 2 pg. P6 Use the Four-Step Plan A used book store had a sale on all paperbacks for $0.45 each. The store had $72.45 in sales. How many books did the store sell?
