We are given the following formula:
Where A is the amount in the account after t years, P is the principal (the initial amount invested), r is the interest rate and t is the time in years.
In this case, P equals 650 ($650), since this is the initial amount invested, r is the rate of interest, which is 0.05 (5%) and t is 6 (6 years). Then:
P = 650
r = 0.05
t = 6
By replacing these values into the above equation, we get:
Then:
A(6) = 877.38
