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?
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}.
Let's assume the number of students who submitted today's assignment is "x".
Ms. Vera spends 5 minutes checking the first two students' work, which is a fixed time.
After that, Ms. Vera spends 1 minute per student.
So, the total time spent by Ms. Vera on checking the remaining (x-2) students' work is (x-2) minutes.
Given that Ms. Vera spent a total of 20 minutes checking both of the "solve on paper" problems assigned, we can set up the following equation:
5 + (x-2) = 20
Simplifying the equation:
x - 2 + 5 = 20
x + 3 = 20
x = 20 - 3
x = 17
Therefore, Ms. Vera checked the work of 17 students.
To solve this problem, we need to set up an equation based on the given information.
Let's assume that the number of students who submitted today's assignment is 'n'.
We know that it takes Ms. Vera 5 minutes to check the first two students' work, and after that, she spends 1 minute per student.
So, for the first two students, she spent 5 minutes. For the remaining (n-2) students, she spent (n-2) minutes.
Therefore, the total time spent by Ms. Vera can be represented as:
5 + (n-2) = 20
To find the value of 'n', let's simplify the equation:
n - 2 = 20 - 5
n - 2 = 15
Now, add 2 to both sides of the equation:
n = 15 + 2
n = 17
So, the number of students who submitted today's assignment is 17.
