Given:
Loan amount = $39,000
Interest rate, r = 4.92% compounded quarterly.
Let's solve for the following:
• (a) Calculate the accumulated amount of this loan at the end of 9 years and 3 months.
To find the accumulated amount apply the formula:
Where:
A is the final amount
P is the loan amount = $39000
r is the interest rate = 4.92% = 0.0492
Since it is compounded quarterly, n = 4
t is the time in years = 9 years 3 months
To write the time in years, we have:
Therefore, to find the accumulated amount, we have:
Solving further:
Therefore, the accumulated amount of this loan at the end of 9 years and 3 months is: $61,306.48
• (b) Calculate the interest charged on this loan.
To calculate the interest, subtract the principal amount from the accumulated loan.
We have:
Interest charged = Accumulated loan - Principal amount
Interest charged = $61,306.48 - $39,000
Interest charged = $22,306.48
Therefore, the interest chrged on this loan is $22,306.48
ANSWER:
• a) $61,306.48
,
• b) $22,306.48
