Answer:
D. Selling the units at $28 will generate the largest profit.
Explanation:
Explanation : Profit = [ ( selling price per unit - variable cost per unit) * units ] - Fixed Cost
Profit at $28 selling price = [ ($28 - $18) * 50,000 units ] - $275,000 = $225,000
Profit at $23 selling price = [ ($23 - $18) * 100,000 units ] - ($275,000 + $100,000) = $125,000
Profit at $25 selling price = [ ($25 - $18) * 75,000 units ] - ($275,000 + $100,000) = $150,000
Thus we can see that profit is largest at $28 per unit selling price
