3 bags of chips and 2 container of dip cost $9. However, 5 bags of chips and 7 containers of dip cost $26. What is the cost of one bag of chips and one container of dip?\r
\n" ); document.write( "\n" ); document.write( "Let the cost of chips be \"c\" and the cost of dip be \"d\". \r
\n" ); document.write( "\n" ); document.write( "3c + 2d = $9 .. equation 1
\n" ); document.write( "5c + 7d = $26 .. equation 2 \r
\n" ); document.write( "\n" ); document.write( "If c = 1, \r
\n" ); document.write( "\n" ); document.write( "3(1) + 2d = $9
\n" ); document.write( "3 + 2d = $9
\n" ); document.write( "2d = 9-3
\n" ); document.write( "d = 6/2
\n" ); document.write( "d = $ 3\r
\n" ); document.write( "\n" ); document.write( "Put c = 1 and d = 3 into equation 2 \r
\n" ); document.write( "\n" ); document.write( "5(1) + 7(3) = 5 + 21 = 26 \r
\n" ); document.write( "\n" ); document.write( "Therefore,the packet of chips is $1 and the dip cost $3.
