Explanation:
Let x be the amount of 15% of gross income.
Given:
Jessica gross income = 48,960.00
She decided to use 15% amount as down payment.
We need to find the amount of 15% of gross income.
Solution:
Using percentage formula.
![percentage = ((Value)/(Total\ value))* 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/ah8skcctqmum34mzld6wcviwas4x8kmsmv.png)
Now we substitute 15 in the place of percentage and 48,960 in the place of Total value.
![15=((x)/(48960))* 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/obkicgpexx8w9h8m7m2z9045n4niq7fpi2.png)
Now, we apply cross multiplication rule.
![x= (48960* 15)/(100)](https://img.qammunity.org/2021/formulas/mathematics/high-school/32fwpc313kzod7bkdvfqnnveodlnrh6oji.png)
![x=48960* 0.15](https://img.qammunity.org/2021/formulas/mathematics/high-school/1vg7s4ys5bqwngvalzz6pvdr9lgwrfya6e.png)
![x =7,344](https://img.qammunity.org/2021/formulas/mathematics/high-school/x0wi6mwxuqwjitmwk50kuom88r82wp4sgn.png)
Therefore: Down payment is 7,344.
