2) Students in an English class took a final exam. They took equivalent forms of the
exam at monthly intervals thereafter. The average score S(t), in percent, after t months
was found to be given by

S(t) = 68 − 20 log (t + 1), t ≥ 0.

3) 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

 1

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 $3,000 for 6 years at a rate of 7%.

a) Calculate the return (A) if the bank compounds semi-annually. Round your
answer to the nearest cent.

Answer:

Show work in this space. Use ^ to indicate the power or use the Equation

Editor in MS Word.

b) Calculate the return (A) if the bank compounds monthly. Round your answer to
the nearest cent.

Answer:

Show work in this space:

c) If a bank compounds continuously, then the formula used is
rt

PeA 
where e is a constant and equals approximately 2.7183.
Calculate A with continuous compounding. Round your answer to the nearest cent.
