a company sells two custom T-shirt and sweatshirt packages. one package contains 10 dozen t-shirts and 14 dozen sweatshirts for $1544. the other package contains 18 dozen T-shirts and 8 dozen sweatshirts for $1472. find the cost of a dozen t-shirts and a dozen sweatshirts\r
\n" ); document.write( "\n" ); document.write( "Assume\r
\n" ); document.write( "\n" ); document.write( "$ x Price of one dozen T shirts
\n" ); document.write( "$ y Price of one dozen sweat shirts
\n" ); document.write( "
\n" ); document.write( " Package 1
\n" ); document.write( "10 x + 14.00 y = 1544.00...............1
\n" ); document.write( "
\n" ); document.write( "Package 2
\n" ); document.write( "18 x + 8.00 y = 1472.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -8
\n" ); document.write( "Multiply (2) by 14
\n" ); document.write( "-80 x -112 y = -12352.00
\n" ); document.write( "252 x 112 y = 20608.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "172.00 x = 8256.00
\n" ); document.write( "
\n" ); document.write( "/ 172.00
\n" ); document.write( "x = 48.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "10.00 x + 14.00 y = 1544.00
\n" ); document.write( "480.00 + 14.00 y = 1544.00
\n" ); document.write( " 14.00 y = 1064.00
\n" ); document.write( " y = 76.00
\n" ); document.write( "Ans x = 48
\n" ); document.write( " y = 76
\n" ); document.write( "$ 48.00 Price of one dozen T shirts
\n" ); document.write( "$ 76.00 Price of one dozen sweat shirts
\n" ); document.write( " \n" ); document.write( "
