Answer:
a. Profit margin = Income from operations / Sales
Profit margin = $73,745/$1,053,500
Profit margin = 0.07
Profit margin = 7%
b. Investment turnover = Sales/Invested assets
Investment turnover = $1,053,500/$245,000
Investment turnover = 4.3 times
c. Rate of return on investment = Profit margin * Investment turnover
Rate of return on investment = 7% * 4.3
Rate of return on investment = 30.10%
