Answer:
ROI = $100 and 20%
Step-by-step explanation:
Return on investment (ROI) is a performance measure used to evaluate a single investment's efficiency in generating profits or to compare the performance of one investment against similar investments in terms of their returns. It is the profit earned per dollar invested and can be calculated as follows:
Selling Price (amount earned) = $ 600
Buying Price (amount spent) = $ 500
Profit on Sale = $100
To calculate the growth in value of the investment: divide the growth value of $100 by the original investment value of $500 to obtain 20% ($100/$500)*100%
