 Question 116885: The formula for calculating the amount of money returned for an initial deposit into a bank account or CD (certificate of deposit) is given by A=P(1+r/n)^rt A is the amount of the return. P is the principal amount initially deposited. r is the annual interest rate (expressed as a decimal). n is the number of compound periods in one year. t is the number of years. Carry all calculations to six decimals on each intermediate step, then round the final answer to the nearest cent. Suppose you deposit \$4,000 for 8 years at a rate of 7%. Calculate the return (A) if the bank compounds monthly (n = 12). Round your answer to the hundredth's place. Click here to see answer by checkley71(8403)
