You deposit $1500 in an account that pays 7% annual interest. Find the balance after 2 years when the interest is compounded daily. 

Remember, the compound interest formula is
 $A=P\left(1+\frac{r}{n}\right)^{nt}$  

You deposit $3000 into a bank account that pays 1.25% annual interest, compounded monthly. What is the balance in the account after 4 years? 

Remember, the compound interest formula is
 $A=P\left(1+\frac{r}{n}\right)^{nt}$
