Question 1140237
the formula as you show it is:


A = P * (1 + r) ^ t


if the interest were compounded 4 times a year, the formula would become:


A = P * (1 + r/4) ^ (t * 4)


the annual interest rate is divided by 4 to get the quarterly interest rate.


the number of years is multiplied by 4 to get the number of quarters.
