1. Sheridan Service has a line of credit loan with the bank. The initial loan balance was $8000.00. Payments of $3000.00 and $4000.00 were made after three months and eight months respectively. At the end of one year, Sheridan Service borrowed an additional $4500.00. Seven months later, the line of credit loan was converted into a collateral mortgage loan. What was the amount of the mortgage loan if the line of credit interest was 7% compounded monthly?
2. A variable rate demand loan showed an initial balance of $8000.00, payments of $3500.00 after six months, $3500.00 after 21 months, and a final payment after six years. Interest was 7% compounded quarterly for the first 21 months and 7.2% compounded monthly for the remaining time. What was the size of the final payment?
Answer is as follows:
Initial loan baalance is $8000.
Rate = 7% per annum
Rate = 7% / 12
= 0.5833%
After 3 months loan amount will be-
Amount after 3 months = loan *(1 + rate)^3
= 8000 *( 1 + 0.005833 )^3
= 8000 *(1.005833)^3
= 8000 * 1.0176
= 8140.81825
Payment after 3 months = $3000
Net balance = Amount after 3 months - payment
= 8140.81825 - 3000
= 5140.81825
Not this net balance will be consier as principal amount for next loan calculation:
Amount after 8 months = Principal * (1 + rate)^5
= 5140.81825 * ( 1 + 0.005833 )^5
= 5140.81825 * (1.005833)^5
= 5140.81825 * 1.029508
= 5292.51832
Payment after 8 months = 4000
Net balance = amount after 8 months - Payment after 8 months
= 5292.51832 - 4000
= 1292.51832
Now, calculate the amount after 12 moths as follows:
Amount after 12 months = Principal * (1 + rate)^4
= 1292.51832 * ( 1 + 0.005833 )^4
=1292.51832 * ( 1.005833 )^4
= 1292.51832 * 1.023538
= 1322.94199
Ammount borrowed after 12 months is 4500.
Net balance = Amount after 12 months + Amount borrowed
= 1322.94199 + 4500.
= 5822.94199
Now. this net balance will be principal amount.
Amount after 7 months = Principal * (1 + rate)^7
= 5822.94199 * ( 1 + 0.005833 )^7
= 5822.94199 * ( 1 .005833 )^7
= 5822.94199 * 1.0415549
= 6064.9138
Therefore, amount of mortgage loan is $6064.9138.
