document.write( "So for your first problem, find C(2), we simply plug 2 into the C(g) equation whereever g is.  Since C(g) = 3.03*g,  then C(2) = 3.03*2 = 6.06.  So C(2) = 6.06.<BR>\n" );

document.write( "I think you may be confusing C(g) to mean C * g.  Note that when we are writing a function C(g), then C(g) is said C OF g, not C times 6.  It may be a little confusing, but C is actually the name of the function, not a variable.  So you don't multiply C with anything! </SPAN>\n" );
