For this problem we can use the formula for the monthly payment formula given by:
![P=(r(PV))/(1-(1+r)^(-n))](https://img.qammunity.org/2023/formulas/mathematics/college/n5beluuqekigfau567p72irdrno114kle9.png)
Where:
P= represent the monthly payment (desired value)
PV= Present value = $15999-1700 = $14299
r= rate of interest per period = 0.04/12
n= number of periods = 12* 6 = 72 months
And if we replace into the monthly payment formula we got:
![P=((0.04)/(12)(14299))/(1-(1+(0.04)/(12))^(-12\cdot6))=\text{ \$223.710}](https://img.qammunity.org/2023/formulas/mathematics/college/11dbmmqiekgh1dvosm0z6aqwpyh7a38elx.png)
And for this case the monthly payment that she can expect is $223.710
