(Do not round until the final answer. Then round to the nearest cent as needed.)
Solution
Solution Steps
Step 1: Convert the annual interest rate from a percentage to a decimal
Given an APR of 8%, we convert this to a decimal: \(r_d = \frac{8}{100} = 0.08\).
Step 2: Calculate the monthly interest rate
The monthly interest rate is calculated by dividing the annual rate by 12: \(r_m = \frac{r_d}{12} = 0.00667\).
Step 3: Calculate the total number of payments
The total number of payments over 4 years is: \(t = n \times 12 = 48\).
Step 4: Use the future value of a series formula to calculate the balance
Using the future value of a series formula: \(FV = P \times \left( \frac{(1 + r_m)^t - 1}{r_m} \right) = 14087.48\).
Final Answer:
The balance of the savings plan after 4 years with an APR of 8% and monthly payments of 250 is approximately $14087.48.
