Assuming the final solution will be diluted to 1.00 , how much more should you add to achieve the desired pH?

Information:
Imagine that you are in chemistry lab and need to make 1.00 L of a solution with a pH of 2.80.
You have in front of you:
100 ml of 7.00×10−2 M HCl,
100 ml of 5.00×10−2 M NaOH and
plenty of distilled water.

You start to add HCl to a beaker of water when someone asks you a question. When you return to your dilution, you accidentally grab the wrong cylinder and add some NaOH. Once you realize your error, you assess the situation. You have 85.0 mL of HCl and 89.0 ml of NaOH left in their original containers.
