Solve the problem.Find the amount in a savings account at the end of 4 years if the amount originally deposited is $8000 and the interest rate is 5% compounded semiannually.Use: A = P
ntwhere:A = final amountP = $8000 (the initial deposit)r = 5% = 0.05 (the annual rate of interest)n = 2 (the number of times interest is compounded each year)t = 4 (the duration of the deposit in years)
