Joseph mixes a certain amount of 10% isopropyl mixture with 60 gallons of a 20% isopropyl solution, and the resulting mixture is 16% isopropyl. How much of the 10% isopropyl did he add? To earn credit, you MUST construct an algebraic equation with a variable and solve using algebra steps.

\n" ); document.write( "Equation:
\n" ); document.write( "iso + iso = iso
\n" ); document.write( "0.10x + 0.20(60) = 0.16(x+60)
\n" ); document.write( "10x + 1200 = 16x + 960
\n" ); document.write( "6x = 240
\n" ); document.write( "x = 40 gallons (amt. of 10% iso needed for the mixture
