Step-by-step explanation

Since we have $4,000, and we need to charge a 15% interest rate, we can apply the following relationship:


A=P\left(1+(r)/(12)\right)^{^(12*t)}

Plugging in the terms into the equation:


A=4000\left(1+(0.15)/(12)\right)^(12*5)-4000

Multiplying terms:


A=4428

Dividing this value into 5 years:


Monthly\text{ payment=}(4428)/(5*12)=73.81

In conclusion, we will need to pay $73.81
