What is the total amount owing on a $300,000 mortgage after 5 years at 7.75% compounded monthly?

What is the total amount owing on a $300,000 mortgage after 5 years at 7.75% compounded monthly?

• A. $385,000.00
• B. $372,555.30
• C. $450,000.00
• D. $360,000.00

Answer: (B)

To determine the total amount owing on a $300,000 mortgage after 5 years at an interest rate of 7.75% compounded monthly, it's important to use the formula for compound interest. The formula for calculating the future value of a loan or investment with compound interest is: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] Where: - \( A \) is the amount of money accumulated after n years, including interest. - \( P \) is the principal amount (the initial amount of money). - \( r \) is the annual interest rate (decimal). - \( n \) is the number of times interest is compounded per year. - \( t \) is the number of years the money is borrowed or invested. In the case of the mortgage: - The principal \( P = 300,000 \). - The annual interest rate \( r = 0.0775 \) (7.75% expressed as a decimal). - Interest is compounded monthly, so \( n = 12 \). - The time period \( t = 5 \) years. Substituting these values into the formula gives: \[ A = 300,

To determine the total amount owing on a $300,000 mortgage after 5 years at an interest rate of 7.75% compounded monthly, it's important to use the formula for compound interest. The formula for calculating the future value of a loan or investment with compound interest is:

[ A = P \left(1 + \frac{r}{n}\right)^{nt} ]

Where:

• ( A ) is the amount of money accumulated after n years, including interest.

• ( P ) is the principal amount (the initial amount of money).

• ( r ) is the annual interest rate (decimal).

• ( n ) is the number of times interest is compounded per year.

• ( t ) is the number of years the money is borrowed or invested.

In the case of the mortgage:

• The principal ( P = 300,000 ).

• The annual interest rate ( r = 0.0775 ) (7.75% expressed as a decimal).

• Interest is compounded monthly, so ( n = 12 ).

• The time period ( t = 5 ) years.

Substituting these values into the formula gives:

A = 300,
