4. Find the accumulated amount A if the principal P is invested at the interest rate of r/year for t years. (Round your answer to the nearest cent.) P = $1200, r = 9 1/2 %, t = 3, compounded annually

A= $

Explanation / Answer

Quarterly rate R= 4%/4 =1%

No. of compounding n = 4x4 =16

FV= 35,177.36

We have following formula for PV:

PV = FV/ (1+r)^n

      = 35,177.36/(1+0.01)^16

       =35,177.36/1.1726

       =29,999.45

amount originally invested is 29,999.45.
