Question 1035836: CKPenny is selling 50 coats. Each coat with a hood have 5 buttons and each coat without a hood have 10 buttons. If there are 400 buttons among all the coats, how many coats don't have hoods? Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let n= coats with hoods
5n+10(50-n)=400
5n+500-10n=400
5n=100
n=20
There are 20 coats with hoods, which have 5 buttons apiece, and 30 coats without hoods, which have 10 buttons apiece!!!!!!!!!!
