A chemistry teacher spends 35 minutes grading 1 students lab. They have 153 students who turn in lab papers for each lab. If the class completed 25 labs, how many minutes will the teacher spend grading lab papers? I just need to know how to set up the problem and the answer, thank you!!

13,3875 minutes or 2,231.25 hours

Explanation:

153 x 25 = 3,825

person x lab paper = all the lab papers turned in.

35 x 3,825 = 13,3875

minutes x all the lab papers turned in = amount of minutes spent on grading
