3) The formula for calculating the amount of money returned for an initial deposit money into a bank account or CD (Certificate of Deposit) is given by



A=P (1+r/n)



A is the amount of returned.



P is the principal amount initially deposited.



r is the annual interest rate (expressed as a decimal).



n is the compound period.



t is the number of years.



Carry all calculations to 6 decimals on all assignments then round the answer to the nearest cent.



Suppose you deposit $10,000 for 2 years at a rate of 10%.



e)What observation can you make about the size of the increase in your return as your compounding increases more frequently?



f) If a bank compounds continuously, then the formula takes a simpler, that is A=PE where e is a constant and equals approximately 2.7183.



Calculate A with continuous compounding.

For continuos compounding the formula is



A=Pe^rt where r is expressed as a decimal and t time in years



A = 10,000 e^(0.1*2)=10,000*1.221403 =$12,214.03
