Final answer:
To calculate the size of the periodic payments, we can use the formula for the present value of an annuity. The size of the periodic payments is approximately $349.89.
Step-by-step explanation:
To calculate the size of the periodic payments, we can use the formula for the present value of an annuity. The present value is equal to the periodic payment multiplied by the present value factor. In this case, the loan has a term of 6 years and the payments are made every 3 months, so there are a total of 24 payments. The interest rate is 5.50% compounded monthly, which means the monthly interest rate is 5.50% divided by 12.
The present value factor can be calculated using the formula:
Present Value Factor = (1 - (1 + r)^(-n)) / r
Where r is the monthly interest rate and n is the number of payments. Plugging in the values:
Present Value Factor = (1 - (1 + 0.055/12)^(-24)) / (0.055/12)
Calculating this expression gives us the value of approximately 20.6073. Now, we can solve for the periodic payment by dividing the loan amount by the present value factor:
Periodic Payment = $7,200 / 20.6073
Using a calculator, we find that the size of the periodic payments is approximately $349.89.
