Determine the periodic deposit. Round up to the nearest dollar. How much of the financial goal comes from deposits and how much comes from interest?

$A=\frac{P[(1+r{)}^t-1]}{r}$

$P=\frac{A(\frac{r}{n})}{[(1+\frac{r}{n}{)}^{nt}-1]}$

Periodic Deposit: $$?$ at the end of each month Rate: $7\mathrm{.}5\%$ compounded monthly Time: $3$ years Financial Goal: $$28,000$
