Answer:
The amount that will go towards the balance is 385.71.
Step-by-step explanation:
The information provided is:
P = Principal of loan = $15,000
r = interest rate = 5.4% p.a. = 
n = number of periods = 36
The amount of the monthly payment that will go towards the balance is:
Amount towards the balance = EMI - Interest
First compute the Equated monthly installments (EMI) as follows:

Now compute the interest as follows:

The amount that will go towards the balance is,
Amount towards the balance = EMI - Interest
= 453.21 - 67.5
= 385.71
Thus, the amount that will go towards the balance is 385.71.
