Question

Full explanation for the answer will be helpful...dont know how to do this lol. medal and fan will be awarded!

The energy produced by a not-quite-perpetual motion machine decreases by 19% per hour. If it produces 24kw in the first hour, how many kw will it produce in total before needing to be restarted?

Answer 1

okay, so basically 19% is 19/100 of the energy source
it will run out in 5 hours because 19 is about 20, and 20x5=100
so 24x5=120?

Answer 2

did it work? sorry, this looks kind of simple, but its the best i could come up with, for it to be more accuate, u should find out what 19/100 is in decimals?
