An amortized loan requires a borrower to repay parts of the loan amount over time. Almost all consumer loans are amortized loans. Amortizing a loan 2 is the process of providing for a loan to be paid off by making regular principal deductions. There are two ways for amortizing a loan. One way is to repay a fixed amount of principal plus a varying amount interest in each period. This approach is common with medium-term business loans. The other is to repay in equal installments, but the composition of principal and interest is varying in each period. For example, a three-month loan of $6000 with monthly interest rate of 2% has the following schedule based on the first way of fixed principals:

Month	Beginning Balance	Monthly Payment	Principal	Interest	Ending Balance
1	$6,000	2,120	2,000	120	4,000
2	$4,000	2,080	2,000	80	2,000
3	$2,000	2,040	2,000	40	0
Totals		$6,240	$6,000	$240

a. Complete the following schedule for the second way of equal installments.
