You can put this solution on YOUR website!
Let x = amount of .08 cement.
\n" ); document.write( "2= amount of .63 cement
\n" ); document.write( "x+2 = amount of .19 cement\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equation to solve is
\n" ); document.write( ".08x + .63*2= .19(x+2)
\n" ); document.write( ".08x + 1.26 =.19x+.38\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract .08x from each side:
\n" ); document.write( ".08x-.08x + 1.26= .19x-.08x + .38
\n" ); document.write( "1.26=.11x + .38\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract .38 from each side:
\n" ); document.write( "1.26-.38 = .11x+.38-.38
\n" ); document.write( ".88=.11x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x=.88/.11= 8 bags\r
