DVD RENTAL FIRM CURRENTLY RENTING 8000 DVD'S PER YEAR.

AND DEMAND RATE IS INCREASING 7%.

YEAR SALE OF PREVIOUS YEAR (A) DEMAND RATE (B) TOTAL VALUE (A+B)
1 8000 7% 8560
2 8560 7% 9159.
3 9159 7% 9800.
4 9800 7% 10486
5 10486 7% 11220
6 11220 7% 12005
7 12005 7% 12845
8 12845 7% 13744
9 13744 7% 14706
10 14706 7% 15735

HERE THE DEMAND AT THE END OF 10 YEARS IS 15735 WITH A CONDITION OF CONSTANT INCREASE IN THE DEMAND RATE EVERY YEAR .

CALCULATION:

FOR FIRST YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

= 8000 +(7% *8000)

= 8000+560

= 8560

FOR SECOND YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

= 8560 +(7%*8560)

=8560+599

= 9159

FOR THIRD YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

=9159+(7%*9159)

=9159+641

=9800

FOR FOURTH YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

= 9800 +(7%*9800)

= 9800+686

= 10486

FOR FIFTH YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

= 10486+ (7%*10486)

= 10486+734

= 11220

FOR SIXTH YEAR = DEMAND OF PREVIOUS YEAR+ DEMAND RATE

= 11220 +(7%*11220)

= 11220+785

=12005

FOR SEVENTH YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

=12005 +(7%*12005)

=12005 +840

=12845

FOR EIGHT YEAR = DEMAND FOR PREVIOUS YEAR + DEMAND RATE

= 12845 +(7%*12845)

=12845 +899

=13744

FOR NINTH YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

= 13744 + (7%*13744)

=14706 +962

FOR TENTH YEAR = DEMAND OF PREVIOUS YEAR + DEMAND RATE

= 14706+ (7%*14706)

=14706 + 1029

= 15735
