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 tmonths 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
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 $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.
