Let n be the number of students who submitted the assignment.
We know that Ms. Vera spends 5 minutes to check the first two students' work and then 1 minute per student, so she spends 5 + 1(n - 2) = 20 minutes.
Thus, 5 + n - 2 = 20
Thus, n - 2 = 15
Thus, n = <<17=17>>17. Answer: \boxed{17}.
Every time Ms. Vera checks a new "solve on paper" problem, it takes her a total of '5 minutes to check the first two students' work. After that, she speeds up and spends I
minute per student. How many students submitted today's assignment if Ms. Vera spent a total of 20 minutes checking both of the "solve on paper" problems assigned?
