9. Method 1 Use a proportion. Example 3 MONEY A CD that originally cost $11.90 is on sale for 30% off. If you have $7, would you have enough money to buy the CD? To determine whether you have enough money to buy the CD, you need to estimate 70% of $11.90. Use Estimation to Solve a Problem

10. Example 3 Use Estimation to Solve a Problem ×3 Since 4 × 3 = 12, multiply 3 by 3. Write the proportion.

11. Example 3 Answer: Since $8.40 is $1.40 more than $7, you would not have enough money. Use Estimation to Solve a Problem Method 2 Use mental math.
