While if only 35% were seated, that means that 65% were not seated. And since it tells us 91 students were not seated, 91 is the 65% of the total amount of students. So we set up a proportion 91/65 =x /100 . When we cross multiply we get 9100=65x, divide by 65 on both sides and get 140=x. Therefore, there were 140 students in all.
It had no executive branch to enforce the laws of the land, congress has no power to tax individual states, and each state printed its own currency.
