You can put this solution on YOUR website!
let x equal the number of yards of blue ribbons.
\n" ); document.write( "let y equal the number of yards of gold ribbons.
\n" ); document.write( "the cost for blue ribbons is equal to 1.99 * x.
\n" ); document.write( "the cost for gold ribbons is equal to 3.50 * y.
\n" ); document.write( "since dana can spend 30 dollars at most, the equation you are looking for is:
\n" ); document.write( "1.99 * x + 3.50 * y <= 30
\n" ); document.write( "the restrictions are that the value of x and the value of y must be greater than or equal to 0.
\n" ); document.write( "this can be defined as:
\n" ); document.write( "x >= 0
\n" ); document.write( "y >= 0
\n" ); document.write( "or as:
\n" ); document.write( "x,y >= 0\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
