So while saying the question, let's further move to the answer.
00:03
So let's see here that.
00:04
So the first one is a house was purchased with the buyer taking out a 30 year, $90 ,000 mortgage at 3 % interest compounded monthly the paid balance of the loan on 31 december just after the $128 payment is equal to $9 ,000.
01:55
20 ,000 into 120 by 100, paid balance is equal to 1 ,08 ,000.
02:24
So the unpaid balance just after the 120th payment is equal to 1 ,08 ,000 minus 90 ,000 is is equal to 18 ,000 and the second one is a is equal to p bracket 1 plus r by 100 to the power and a is equal to 90 ,000 bracket 1 plus 3 by 100 to the power to a is equal to 9 .10 to 103 is equal to 95 ,481.
04:13
So i is equal to a minus p is equal to 95 ,481 minus 90 ,000 is equal to 5 ,481.
04:29
So here is the solution of the question that, so the first one, a house was purchased with the buyer taking out of 30 year $90 ,000 mortgage at 3 % interest compounded monthly.
