You can put this solution on YOUR website!
Try this:
\n" ); document.write( "Let x = the required number of pounds of raisins @ $3.00 per pound.
\n" ); document.write( "$3.00(x)+$2.40(10) = $2.80(10+x) Simplify and solve for x.
\n" ); document.write( "3x+24 = 28+2.8x Subtract 2.8x from both sides.
\n" ); document.write( "0.2x+24 = 28 Subtract 24 from both sides.
\n" ); document.write( "0.2x = 4 Finally, divide both sides by 0.2
\n" ); document.write( "x = 20
\n" ); document.write( "You will need 20 pounds of raisins. \n" ); document.write( "

\n" );
