let x be the cost of his meal, then
\n" ); document.write( ".20 * x = 7.50
\n" ); document.write( "x = 7.50 / .20
\n" ); document.write( "x = 37.50, therefore
\n" ); document.write( "the cost of his meal is $37.50
\n" ); document.write( "now we want 37.50 + 7.50 = $45.00
\n" ); document.write( "the cost of his meal plus tip is $45.00
\n" ); document.write( "
\n" ); document.write( "
\n" );
