You can put this solution on YOUR website!
1.) assign variables, x=cones, y=sundaes
\n" ); document.write( "2.) set it up as a system of equations, this is how you set it up,
\n" ); document.write( " x + y=172
\n" ); document.write( "1.1x+2.35y=294.2
\n" ); document.write( "3.)solve for a variable by substitution of elimination. I think elimination would be easiest.
\n" ); document.write( "4.) multiply the top equation by -1.1 so the x's will cancel, now you have
\n" ); document.write( "-1.1x + -1.1y= -189.2, for the top equation
\n" ); document.write( " 1.1x + 2.35y=294.2, for the bottom equation
\n" ); document.write( "5.) you add the two equations together. the x's cancel and you have
\n" ); document.write( "1.25y=105, solve for y by dividing 105 by 1.25. y =84
\n" ); document.write( "6.) plug 84 back into one of the original equations for y
\n" ); document.write( "x + 84 = 172, subtract 84 from both sides x=88
\n" ); document.write( "88 cones were sold and 84 sundaes were sold
\n" ); document.write( " \r
