Question

A utility company in a western city of the United States expects the consumption of electricity to increase by 11%/year during the next decade, due mainly to the expected increase in population. If consumption does increase at this rate, find the amount by which the utility company will have to increase its generating capacity in order to meet the needs of the area at the end of the decade.

Answer 1

1.11^9 if you consider 9 years left until the end of this decade.

Answer 2

Answer 10

oh I think I got it now :)

Answer 11

if the consumption increases 11% ------> every 1 year
then how much will it increase (x)-------> in 9 years?

are you aware of this way? we have the following now:

11%---------> 1 year
x (%) --------> 9 years


cross multiply and you'll get :

x(%) = (11)% (9)
x = 99%

I guess, I'm not sure though :) correct me please if I'm wrong ^_^
