Ok well first we must make a table like this... \r
\n" ); document.write( "\n" ); document.write( " Amt. $ Total
\n" ); document.write( "Raisins r 2.20 2.20r
\n" ); document.write( "Nuts 15 4.00 60
\n" ); document.write( "Total 15+r 3.00 (15+r)3\r
\n" ); document.write( "\n" ); document.write( "Now we have to write an equation which would be 2.2r+60=(15+r)3 then we would distribute the three to get 2.2r+60=45+3r Then subtract both sides by 45 to get 2.2r+15=3r. Now subtract each side by 2.2r to get 15=.8r. Now multiply each side by 10 to get rid of the decimal thus getting 150=8r. Then divide both sides by 8 to get r=18.5. So you would need 18.5 pounds of raisins. Hope this helps!!
