Question 285599: How would i put this into two equations.
1 gallon of milk cost $3 and a family of 4 buys 12 galoons a month. How much is being spent on milk for a month.
X= gallons of milk Y= amount spent per month

Answer by josmiceli(19441) About Me  (Show Source):
You can put this solution on YOUR website!
(cost of milk)/(gallon) x (gallons/month) = (cost of milk)/(month)
%283%2F1%29%2A12+=+Y
Y+=+36 dollars/month
3X=+36
X+=+12 gallons/month
I'm not sure why equations are needed
