A motorcycle uses 50 000 kilojoules per minute. If 15 percent of the 15 energy generated by its engine is lost in the first few seconds, how much energy, in kilojoules, remains to power the motorcycle?

15% is lost means 85% is still available, right ?

OpenStudy (weasel123):

yea

OpenStudy (rational):

Then I guess you just need to take 85% of the starting energy to get the remaining energy

OpenStudy (rational):

Do you know how to take percentages ?

OpenStudy (weasel123):

i think so
