Forgot the equation?

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)^nt



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%.



A) If a bank compounds continuously, then the formula used is A = Pe^(rt)



where e is a constant and equals approximately 2.7183.



Calculate A with continuous compounding. Round your answer to the hundredth%26#039;s place.
