Initial investment or PV of Cash Outflow at Year 0= -170000

Number of Years to 10 Years(n) = 10-0= 10

Interest rate (i)= 12%

Future Value of single Present Value = PV*(1+i)^n

=-170000*(1+12%)^10

=-527994.1954

Annual Cash inflows each year (P)=40000

Number of years for which it is received (n)=10

FV of Annuity Formula =P*(((1+I)^n)-1)/I

=40000*(((1+12%)^10)-1)/12%

=701949.4028

Salvage value Received at year 10 or single PV= 30000

Years gap at 10(n)= 10-10= 0

Future Value of single Present Value = PV*(1+i)^n

=30000*(1+12%)^0

=30000

Future worth of Investment is Future Value of all Cash Flows

Future worth = Sum of all Cash Flow

=-527994.1954+701949.4028+30000

=203955.21

So future worth of Investment is $203955.21
