Answer:

$323

Step-by-step explanation:

The monthly payment can be calculated using the formula:

$M=\frac{P(\frac{r}{12})(1+\frac{r}{12})^n}{(1+\frac{1}{12})^n-1}\\\\$

where:

M=monthly payment
P=amount borrowed
r=annual interest rate
n=total number of monthly payments:

Our parameters are defined as:

$n=60\\P=21000-4000=17000\\r=5.3%\\\\$

We plug our parameters in the equation to solve for M;

$M=M=\frac{P(\frac{0.053}{12})(1+\frac{0.053}{12})^n}{(1+\frac{0.053}{12})^{60}-1}\\\\\\\\$

$=\frac{P(\frac{0.053}{12})(1+\frac{0.053}{12})^{60}}{(1+\frac{0.053}{12})^{60}-1}\\\\\\=323.15$

$=323.15\approx\$323$

Hence, the monthly payment is $323
