Hi!
I have come across this question in my math practice
The nations energy comes from 40% oil, 45% from coal, and the rest from its 450 wind turbines. The government estimates that in a decade, energy demand will have risen by 20%, but oil reserves will have fallen by 10% and coal by 8%.
How many more wind turbines must be built?
As far as my calculations go, in a decade 678 wind turbines will be needed, so the answer would be that 228 more have to be built.
Could you please verify this?
Thank you so much in advance!
Thank you so much, Hagen, for the quick reply! This helps a lot! I totally ignored the statement that it will increase by 20%! It all makes sense now :)
