i would say more peanuts than caramel popcorn.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "here's why:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let c = number of pounds of caramel popcorn
\n" ); document.write( "let p = number of pounds of peanuts\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "peanuts costs 3.10 per pound.
\n" ); document.write( "total cost of peanuts is therefore 3.10 * p\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "caramel popcorn costs 2.30 per pound.
\n" ); document.write( "total cost of caramel popcorn is therefore 2.30 * c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your formula is 3.10 * p + 2.30 * c = 2.80 * (p + c)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify by distributing the multiplication on the right side of the equation to get 3.10 * p + 2.30 * c = 2.80 * p + 2.80 * c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract 2.80 * p from both sides of the equation and subtract 2.30 * c from both sides of the equation to get 3.10 * p - 2.80 * p = 2.80 * c - 2.30 * c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify to get .30 * p = .50 * c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "divide both sides of the equation by .30 to get p = (.50 / .30) * c = 5/3 * c.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this means that p > c\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let's see if that's true.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "assume c = 3 pounds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this makes p = 5/3 * 3 = 5 pounds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "original formula says:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3.10 * p + 2.30 * c = 2.80 * (p + c)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since p = 5 and c = 3, this formula becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3.10 * 5 + 2.30 * 3 = 2.80 * 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "22.4 = 22.4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solution looks good.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the mixture contains more peanuts than caramel popcorn.\r
