Answer:
$105,075
Explanation:
The computation of the operating income is shown below:
Sales (4 × 69,500) $278,000
Less:Variable costs (0.95 × 69,500 + 5% × 278,000) $79,925
Contribution margin $198,075
Less: fixed cost (13,000 + 80,000) $93,000
Net operating income $105,075
We simply deduct the variable cost and the fixed cost from the sales to arrive at the net operating income
