Question 766652
The kayla's and cody's ice cream store sells ice cream shakes made of ice cream and milk. The milk used has 2% fat and the ice cream had 30% fat. Anna is in charge of making shakes. Today's mix had a total of 23% fat. If Anna used three quarts of milk, how many quarts does the entire mixture contain?
***
let x=number of quarts of 23% fat mixture
x-3=quarts of 30% fat ice cream used
2%*3+30%(x-3)=23%x
.06+.30x-.90=.23x
.07x=.84
x=12
how many quarts does the entire 23% fat mixture contain? 12
