Final answer:
The total interest paid on a $7000 loan at 6.5% APR over 39 months is $1478.75, calculated using the simple interest formula.
Step-by-step explanation:
To calculate the total interest paid on a $7000 loan for 39 months at a 6.5% APR, we use the simple interest formula, I = PRT, where I is the interest, P is the principal amount, R is the annual interest rate in decimal form, and T is the time in years.
First, convert the interest rate from a percentage to a decimal by dividing by 100:
R = 6.5 / 100 = 0.065.
Next, convert the loan period from months to years:
T = 39 months / 12 = 3.25 years.
Now, apply the values to the formula:
I = $7000 * 0.065 * 3.25.
I = $7000 * 0.21125.
I = $1478.75.
Thus, the total interest paid after 39 months is $1478.75.
