Remember that the formula for interest problems is: A = P(1+(i/n))nt
where A = amount
         P = principal (the dollars you start with)
         i = annual interest rate
         n = number of times compounded per year
         t = number of years
In this problem P = 700, i = 0.085, n = 4 (quarterly), and t = 10
So, the equation becomes  A = 700(1 + (0.085/4))4*10
If 8.5% is the APR, annual percentage rate, then the total sum after 10 years will be
If it is the interest rate in one quarter, then
