4. Example 1 Use the Solve a Simpler Problem Strategy BAKE SALE Elmwood Middle School received 620 contributions for its bake sale. If 40% of the contributions were cookies, how many cookies did the school receive? UnderstandYou know the school received 620 contributions, and 40% of them were cookies. You need to find the number of cookies the school received. PlanSolve a simpler problem by finding 10% of the number of contributions and then use the result to find 40% of the number of contributions.

5. Example 1 Use the Solve a Simpler Problem Strategy Answer: So, the school received 248 cookies. Solve 620 ÷ 10 = 62 contributions Since there are four 10% in 40%, multiply 62 by 4. 62 × 4 = 248 Check
