The problem states, for instance, "Suppose you deposit 700 dollars into a bank with 8% simple interest. The amount in the account after years is given by A(t) = 700 (1.08)^t (in dollars)." The problem says "simple interest", but then gives the formula for compound interest compounded annually. I'm duplicating and editing it locally to say "interest compounded annually" instead of "simple interest", but really think that it's pretty bad that the base problem has this sort of error.
