Eight hot dogs and seven hot dog rolls cost . Seven hot dogs and eight hot dog rolls cost . How much, in dollars, does a hot dog and a hot dog roll cost combined?

I think this site needs latex to be enabled.

 

You can't copy latex since it won't show.

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

Thanks, gwen, what I meant was that you have to click the latex button.
