Answer:
Operating income increases by $40,000.
Explanation:
Given that,
Total fixed costs = $840,000
Sale price per unit = $60
Variable cost per unit = $30
Additional amount spend on advertising = $35,000
Sales volume would increase by 2,500 units.
Contribution margin:
= Sales - Variable costs
= $60 - $30
= $30 per unit
Increase in operating income:
= Increase in contribution margin - Increase in Fixed costs
= ($30 × 2,500 units) - $35,000
= $75,000 - $35,000
= $40,000
