You can put this solution on YOUR website!
Good up thru about half way
\n" ); document.write( "\"900%2F%28x-5%29+-+900%2Fx+=+2\" difference is $2
\n" ); document.write( "\"900x+-+900%28x-5%29+=+2%2A%28x%29%2A%28x-5%29\"
\n" ); document.write( "\"4500+=+2%28x%5E2-5x%29\"
\n" ); document.write( "\"0+=+x%5E2+-+5x+-+2250\"
\n" ); document.write( "\"0+=+%28x-50%29%28x%2B45%29\"
\n" ); document.write( "Since the cost ,x, must be positive, the only answer option is x=50
\n" ); document.write( "Verify your answer, is 900/50 2 dollars less than 900/45???\r
