How many gallons of milk containing 1% fat is mixed with milk containing 4% fat to obtain a 15 gallon mixture containing 2% fat?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of 4% fat milk required to accomplish this
\n" ); document.write( "the total is to be 15 gal, therefore:
\n" ); document.write( "(15-x) = amt of 1% fat milk needed
\n" ); document.write( ";
\n" ); document.write( "A typical mixture equation using the decimal equiv
\n" ); document.write( ".01(15-x) + .04x = .02(15)
\n" ); document.write( ".15 - .01x + .04x = .30
\n" ); document.write( "-.01x + .04x = .30 - .15
\n" ); document.write( ".03x = .15
\n" ); document.write( "x = .15/.03
\n" ); document.write( "x = 5 gal of 4% milk is needed
\n" ); document.write( "then
\n" ); document.write( "15 - 5 = 10 gal of 1% milk
\n" ); document.write( ":
\n" ); document.write( ":
