Answer:
$13.68
Explanation:
Assuming they rent for 1 year, the cost is broken down as follows:
Annual renting cost = 22% of 722.98 =
![(22)/(100)*722.98=0.22*722.98=159.06](https://img.qammunity.org/2020/formulas/mathematics/middle-school/l6crvu9jrpzq5qaygd2fd3rweuwz7ytzyp.png)
Usage charge = 3.2% of 159.06 =
![(3.2)/(100)*159.06=0.032*159.06=5.09](https://img.qammunity.org/2020/formulas/mathematics/middle-school/e1pqif2cz4f5i03eospbg1rfbmfmx09wkt.png)
Thus,
Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15
Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):
