Answer: Option C is most reasonable here.
Explanation:
Variable Price of Bulb A = $ 15,000
Variable Price of Bulb B = $ 28,000
Variable Price of Bulb C = $ 16,200
Fixed Price of Bulb A = $ 15,000
Fixed Price of Bulb B = $ 30,000
Fixed Price of Bulb C = $ 25,000
Total Price of Bulb A = $30,000
Total Price of Bulb B = $ 58,000
Total Price of Bulb C = $ 41,200
Profit= Revenue - Expenses
Profit of Bulb A = $ 16,500
Profit of Bulb B = $ 30,000
Profit of Bulb C = $ 25,400
Initial Investment of Bulb A = $ 30,000
Initial Investment of Bulb B = $ 60,000
Initial Investment of Bulb C = $ 40,000
Hence, Bulb C is most profitable.
