The cheerleaders sold foam fingers for $5 and spirit bracelets for $4. They sold 40 more foam fingers than bracelets, and they earned $965. Write a system of equations to describe the situation and solve this system using at least two different methods and explain each method.
\n" ); document.write( "so far this is what i have and i'm not sure if its correct can't get past anything else.
\n" ); document.write( "5.00x+4.00y=965
\n" ); document.write( "x+y=40 more foam fingers
\n" ); document.write( "
\r\n" );
document.write( "Your first equation is right, although you don't need\r\n" );
document.write( "the decimals and 0's, just this\r\n" );
document.write( "\r\n" );
document.write( "\"5x%2B4y=965\"\r\n" );
document.write( "\r\n" );
document.write( "But your second equation is wrong.\r\n" );
document.write( "\r\n" );
document.write( "Look at this sentence:\r\n" );
document.write( "\r\n" );
document.write( ">>..They sold 40 more foam fingers than bracelets..<<\r\n" );
document.write( "\r\n" );
document.write( "Think about it!  You have more foam fingers and fewer bracelets\r\n" );
document.write( "\r\n" );
document.write( "So to get the number of foam fingers, you must add 40 to the\r\n" );
document.write( "number of bracelets.  So the correct equation is\r\n" );
document.write( "\r\n" );
document.write( "Foam fingers = bracelets + 40 \r\n" );
document.write( "\r\n" );
document.write( "\"x+=+y+%2B+40\"\r\n" );
document.write( "\r\n" );
document.write( "So you have this system:\r\n" );
document.write( "\r\n" );
document.write( "\"system%285x%2B4y=965%2C+x=y%2B40%29\"\r\n" );
document.write( "\r\n" );
document.write( "Can you solve that by two different methods?  If not post \r\n" );
document.write( "again asking how.  Two different methods would be\r\n" );
document.write( "(1) substitution and (2) elimination.\r\n" );
document.write( "\r\n" );
document.write( "Solution: \"x=125\", \"y=85\"\r\n" );
