Answer:
8.65%
Explanation:
We have been given that Debra earns $4740 per month. Every month she saves $410. Additionally, she has $2520 in outstanding credit cards and makes a $210 monthly payment of these cards.
![\text{Savings ratio}=\frac{\text{Savings}}{\text{Income}}* 100\%](https://img.qammunity.org/2021/formulas/mathematics/high-school/gllsuww50m12vve7fx885kcak8nx45ep23.png)
Upon substituting our given values in above formula, we will get:
![\text{Savings ratio}=(410)/(4740)* 100\%](https://img.qammunity.org/2021/formulas/mathematics/high-school/q17tvmcjjdg7aix8e9a46v5tb3t3xskqc2.png)
![\text{Savings ratio}=0.08649789* 100\%](https://img.qammunity.org/2021/formulas/mathematics/high-school/5elsvee1kq0hg7h6998n5rv1178ub65avi.png)
