# Return on Investment

$$
ROI = \frac{\[Value of Investment - Cost of Investment] \* 100} { \[Cost of Investment]}
$$

Cost of Investment = $100,000

Value of Investment = $145,000

$$
ROI = \frac{\[145,000 - 100,000] \* 100} { \[100,000]} = \frac{\[45,\sout{000}] \* \sout{100}} { \[\sout{100,000}]}
$$

ROI = 45 %
