I can help with most of the questions, but these are quite many given most of them require mathematical calculations. At your current offer I can answer 6-7 questions at a time. That would be 4-5 sets for total of 30 questions. Please let me know if it's acceptable to you as multiple sets.

I am not satisfied with that. I have seen your work and you have answered more then 20 for the same amount of money. I would be satisfied with the first 20 questions from this list.

Alright, I hope you'd be able to afford more. What time are the answers due? And as I said before, I'm not sure about a few. I hope that's ok with you.
