Explanation / Answer

Investment A

Monthly Investment =$1900

n(period) = 144 payments

Interest =8.3 % compunded monthly

Future value of Investment A =$469709.94

Investment B

So we need to pay a lump sum investment to get Future value of investment of B as $469710.

A = Pert, whre A is Future value, P is the Principal, r is the interest rate and t is time

469710 = Pe0.0780*12

P = 469710/e0.936

P= 469710/2.54796

P= 184217.20
