Answer and Explanation:
The computation is shown below:
Contribution Margin for Bat
= $50 - $50
= $0
Contribution Margin for Gloves = $100 - $80
= $20
Now
Overall Contribution Margin = (0 ×70%) + ($20 × 30%)
= $0 + $6
= $6
Now
A. Break even sales = Fixed cost ÷ contribution margin
= $57,000 ÷ $6
= 9,500
B.Baseball bats = 9,500 × 70% =6,650
Baseball Gloves = 9,500 × 30% = 2,850
