question 9 (1 point) charlie invested $2,200 last year. his investment is now valued at $2,750. which of the following correctly shows how to calculate return on investment (roi)?\no a $\frac{2750 - 2200}{2750}cdot100$\no b $\frac{2750 - 2200}{2200}cdot100$\no c $\frac{2200 - 2750}{2200}cdot100$\no d $\frac{2200 - 2750}{2750}cdot100$

Answer

Explanation:

Step1: Recall ROI formula

ROI = $\frac{\text{Current Value}-\text{Cost of Investment}}{\text{Cost of Investment}}\times100$

Step2: Identify values

The cost of investment is $2200$ and the current value is $2750$.

Step3: Substitute values

Substituting into the formula gives $\frac{2750 - 2200}{2200}\times100$.

Answer:

B. $\frac{2750 - 2200}{2200}\times100$
