4. Edgar saw the following items at a store: a batting glove for $8
Edgar saw the following items at a store: a batting glove for $8.95, inline skates for $39.75, weights for $5.50 each, and a can of tennis balls for $2.75. Which items can Edgar buy and spend about $15?
Example 1

5. Understand What facts do you know?
The cost of the items and that Edgar has $15 to spend.
What do you need to find?
You need to find which items Edgar can buy that cost about $15 total.
Example 1

6. Plan One way to solve the problem is by making an organized list.
Example 1

7. Solve
Since the inline skates cost more than $15, you can eliminate the inline skates as an option. Round the costs of the other items to the nearest dollar.
Batting glove: $8.95 ≈ $9
Weights: $5.50 ≈ $6
Can of tennis balls: $2.75 ≈ $3
Example 1

8. Solve Start with the batting glove:
1 glove + 1 weight ≈ $9 + $6, or $15
1 glove + 2 cans of tennis balls ≈ $9 + $6, or $15
List other combinations that contain the weights:
2 weights + 1 can of tennis balls ≈ $12 + $3, or $15
1 weight + 3 cans of tennis balls ≈ $6 + $9, or $15
Example 1

9. Solve List any remaining combinations that contain the tennis balls:
5 cans of tennis balls ≈ $15
Example 1

10. Check
Check the list to be sure that all of the possible combinations of sporting good items that total no more than $15 are included.
