Answer: Ok while i was working out this problem I started by multiplying so i started by 5
2.50 x 5 = 12.5
3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.
2.50 x 7 = 17.5
3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..
2.50 x 9 = 22.5
3.25 x 9 = 29.25 and that equaled 51.75
so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.
