Answer
Explanation:
Step1: Identify cost and benefit
Cost = $9000$, Benefit = $600000$
Step2: Calculate ROI
ROI formula is $\text{ROI}=\frac{\text{Benefit}-\text{Cost}}{\text{Cost}}\times 100%$. Substituting values: $\text{ROI}=\frac{600000 - 9000}{9000}\times 100%=\frac{591000}{9000}\times 100%\approx 6566.67%>0$
