Question 1182803

I took a math assessment and had difficulty solving the following problem:  

"Diana and James were selling tickets for their upcoming softball game.  James sold 20% more than Diana. If they sold 55 tickets total, how many tickets did each of them sell?"

I do not know the steps to solve this problem.

<pre>Let number that Diana sold be D
Then James sold 1.2D
With both selling 55, we get: D + 1.2D = 55
                                  2.2D = 55
              Number Diana sold, or {{{highlight_green(matrix(1,5, D, "=", 55/2.2,"=", 25))}}}
              Number James sold: {{{highlight_green(matrix(1,7, 1.2D, "=", 1.2(25), "or", 55 - 25,"=", 30))}}}
