Emi takes out a reducing balance loan of $500 000.

The interest rate is 5.3% per annum, compounding monthly.

Emi makes regular monthly repayments of $3071.63 for the duration of the loan, with only the final repayment amount being slightly different from all the other repayments.

Determine the total cost of Emi's loan, rounding your answer to the nearest cent, and state the number of payments required to fully repay the loan. (2 marks)

$\text{Using CAS: Find number of payments to give a nil balance owing.}$

$\text{Using CAS: Find amount still owing if 288 payments are made.}$

$\therefore\ \text{Final payment}\ =$3071.63+$4.18 =$3075.81$

• Interest compounds monthly.
• After the first monthly payment has been made, the amount owing on the loan is $299 000.

Which one of the following statements is true?

After two months, $297 995 is still owing on the loan.
$1000 of interest has been paid in the first month.
The loan will be fully repaid in less than 15 years.
Halfway through the term of the loan, the amount still owing will be $150 000.
Payments of $2750 rather than $2500 per month will reduce the time to repay the loan fully by more than three years.
