D = Investment Amount (5000)
P = Interest (5.25)
Y = Number of Years (2.25)
M = Conversions/Year (4)
Use the following formula to calculate the Maturity value (S:
S = D ( 1 + P/M)^YM
If you use the sample data provided above, S will equal 5622.60.
HINT:  Be sure to divide the interest by 100 to get the correct mathematical value (e.g. 0.0525)
