+45 I think this site needs latex to be enabled.
You can't copy latex since it won't show.
+781 Latex is enabled, but you can't just simply copy and paste the latex here to show up. You have to press the latex button when typing a response and then enter your latex.
You don't need Latex to write down a dollar amount. Just write it down.
As an example of a dollar amount: $14.50 ... you just type it in.
What you would do is create a pair of equations and solve for the values.
8D + 7R = nn.nn
7D + 8R = pp.pp

+680 Yeah, but this guy probably copied and pasted it so it didn't appear! 
+45 Thanks, gwen, what I meant was that you have to click the latex button.
