Use the compound intrest formula to find the oresent value P
Use the compound intrest formula to find the oresent value P, for the following given values.
A= $15,900
i=0.066
n=98
P=? (round to the nearest cent)
Solution
Continuously compounded interest formula , A=P.ei.n ...............(i)
where, P=the principle amount
i=annual interest rate
n=number of years P is invested
A=amount after n years.
Given, A=15900, i=0.066, n=98
We have to find P.
From equation (i), puttiin values of A, i, n we get,
P=15900xe-(0.066x98) =24.68200382
Therefore, P=$24.68200382=(24.68200382x100) cents= 2468cents
