Algebra.Com's Answer #41638 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=amt of milk (gal) to be mixed \n" ); document.write( "Then 35-x=amt of whipping cream (gal) to be mixed \n" ); document.write( "We know that the amt of butterfat in the milk (x)(.02) plus the amt of butterfat in the whipping cream (35-x)(.09) equals the amt of butterfat in the final mixture (35)(.04). Thus, our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "(x)(.02)+(35-x)(.09)=(35)(.04) simplifying, we get \n" ); document.write( ".02x+3.15-.09x=1.4 further simplifying, we have \n" ); document.write( "-.07x=-1.75 \n" ); document.write( "x=25 gal \n" ); document.write( "We need 25 gal of milk and 35-25=10 gal of whipping cream \n" ); document.write( "Hope this helps ----ptaylor \n" ); document.write( " |
