Rebekah's commission rate is 16%. She invests her commission from the sale of 18,000$ worth of merchandise at the interest rate of 5%, compounded quarterly. How much is Rebekah's investment worth after 6 months?
------
Her commission before investing it:: 0.16*18000 = 2880
------------
Formula for compound investing::
A(t) = P(1+(r/n))^(nt)
------
Value of her investment::
A(1/2) = 2880(1+(0.05/4))^(4*(1/2)
----
A(1/2) = 2880(1.0125)^(2)
---
A(1/2) = 2880*1.025
A(1/2) = $2952.45
