Answer: please refer to the explanation section
Explanation:
The question is incomplete to calculate Return on investment we need the investment amount (the Purchase price of the new production capacity acquired), to illustrate how Return on Investment is Calculated we will assume 20000 units of additional capacity were purchased at a price $ 400000
Bing's units = 20000
selling price = $10
Direct Material = $3
Direct labour cost = $5
Total costs =(20000 x $3) - (20000 x 5) = $160000
Revenue = 20000 x $10 = $200000
Profit = $200000 - $160000 = $40000
Return on Investments
Return on investments = net profit/purchase price
Return on investments = 40000/400000 = 0.1 x 100 = 100%
