Final answer:
To calculate the loan balance after the 3-year grace period, use the compound interest formula: A = P(1 + r/n)^(nt). Plugging in the values, the loan balance is approximately $3017.32.
Step-by-step explanation:
To calculate the loan balance after the 3-year grace period, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
- A is the loan balance after the grace period
- P is the initial loan amount ($2450)
- r is the interest rate per period (7.8% = 0.078)
- n is the number of compounding periods per year (52)
- t is the number of years (3)
Plugging in the values, we get:
A = 2450(1 + 0.078/52)^(52*3)
Calculating this expression, the loan balance after the 3-year grace period is approximately $3017.32.
