1-1 Using a Problem-Solving Plan (Pages 6?10)

You can use a four-step plan to solve real-life, math-related problems.

Explore Plan Solve Examine

Read the problem carefully. Ask yourself questions like "What facts do I know?" and "What do I need to find out?"

See how the facts relate to each other. Make a plan for solving the problem. Estimate the answer.

Use your plan to solve the problem. If your plan does not work, revise it or make a new one.

Reread the problem. Ask, "Is my answer close to my estimate? Does my answer make sense for the problem?" If not, solve the problem another way.

Example

Luther bought 8 CDs at a sale. The first CD purchased costs $13, and each additional CD costs $6. What was the total cost before tax?

Explore Plan Solve Examine

You are given the cost of the first CD and the cost of additional CDs. You need to find the total cost.

First find the number of additional CDs after the first CD he purchased. Multiply that number by $6 and add $13 for the first CD. Estimate the total cost by using $15 7 $5 $50. 8 1 7, 7 $6 $42, $42 $13 $55 The total cost of $55 is close to the estimate of $50, so the answer is reasonable.
