Question

Darren teaches a class of 25 students. He assigns homework 3 times a week, and each assignment consists of 12 problems. How many problems must Darren correct each week?

A.
225 problems
B.
890 problems
C.
900 problems
D.
1,000 problems

Answer 1

For this case we have that each week assign 3 tasks, each of 12 problems, then multiply:

`3 * 12 = 36`

Thus, assign 36 weekly problems to each student. Darren has 25 students, so, multiplying, we have:

`36 * 25 = 900`

Thus, Darren must correct 900 weekly problems.

Answer:

Option C

Answer 2

Option C is correct.

Explanation:

Homework is assigned: 3 times a week

Each assignment consists problems = 12

Total questions in 1 week = 12*3 = 36

Total no of students = 25

So, Problems Darren must correct each week = Total no of students * Total questions in 1 week

Problems Darren must correct each week = 25*36

Problems Darren must correct each week = 900

So, Option C is correct.
