A bank features a savings account that has an annual percentage rate of $r = 3.7\%$ with interest compounded quarterly. Lola deposits $9,000 into the account. The account balance can be modeled by the exponential formula $S(t) = P(1 + \frac{r}{n})^{nt}$, where $S$ is the future value, $P$ is the present value, $r$ is the annual percentage rate written as a decimal, $n$ is the number of times each year that the interest is compounded, and $t$ is the time in years. (A) What values should be used for $P$, $r$, and $n$? $P = \text{_____}$, $r = \text{_____}$, $n = \text{_____}$ (B) How much money will Lola have in the account in 7 years? Answer = $\$$_____
