Hi there in this question it is given that the principal amount p is equal to $60 ,000.
00:05
The interest rate is 5 % and the number of years is 25 years.
00:11
And here in a part we have to find capital a equal to p multiplied by 1 plus r divided by 12 to the part n.
00:19
In the b part we have to find capital b is equal to 1 plus r divided by 12 whole power n minus 1 divided by r divided by r divided by 12.
00:31
And in the c part, we have to find r is equal to a divided by b, where r is the amount that is necessary to, that, the monthly payment that is necessary to pay off the loan.
00:42
So let's see how we'll do this.
00:45
So in the first case, we have a is equal to p multiplied by 1 plus r divided by 12 to the power n.
00:51
That is this is equal to 60 ,000 multiplied by 1 plus 5 divided by 12 to the power 25.
01:01
So here we'll be having this is equal to 60 ,000 multiplied by 1 .417 to the power 25.
01:14
That is equal to 60 ,000 multiplied by 6 ,049 .12.
01:25
And this product will be equal to, this is equal to 362.
01:35
946 956.
01:37
So we got this value here.
01:39
So a is equal to 362 -946 -9 -56.
01:45
So we got the value of a here.
01:48
This is the required value of a...
