Final answer:
Kerry should make the investment in the cosmetic stand as the return on investment is 2166%, which is significantly higher than the expected risk return of 10%.
Step-by-step explanation:
To determine whether Kerry should make the investment in the cosmetic stand, we need to calculate the return on investment (ROI). ROI is calculated by dividing the after-tax cash flow by the initial investment, and then expressing it as a percentage.
The after-tax cash flow for 10 years is $541,500 per year, which amounts to a total of $5,415,000 over 10 years. The initial investment is $250,000.
The ROI can be calculated as: ROI = ($5,415,000 / $250,000) * 100% = 2166%.
Based on the given information, Kerry would earn an ROI of 2166%, which is significantly higher than the appropriate risk return of 10% that Kerry expects. Therefore, Kerry should definitely make the investment.
