Interest and Loan Concepts Assignment (Total 40 Points)

Question 1: (10 Points)

a) State the simple interest formula and explain how simple interest is calculated.
To calculate simple interest you will use the following formula.
I = PRT (I = Interest, P = principal, R = rate, and T = time
To find the interest you will first convert the rate to a decimal (E.g 3.5% = 0.035) and then you would replace the P with the amount of the loan, replace R with the rate converted to a decimal and replace the T will the duration of the loan (E.g 1yr, 2yrs etc..). Once the numbers are inputted you would multiple across to get the interest amount.

b) Calculate the simple interest for a loan for $39,545 for 3 1/2 years at 7.5% interest per year. Round to the nearest cent.
I = PRT
I = 39,545 (7.5%) (3.5) = 39,545 (0.075) (3.5) = 10,380.56
Thus, the interest on the loan is $10,380.56

c) How much is owed in total at the maturity date?
$39,545 +
