Final answer:
Mr. Clark gave out 125 sheets of paper.
Step-by-step explanation:
To find the total number of sheets of paper Mr. Clark gave out, we can multiply the number of students by the number of sheets of paper each student received. In this case, Mr. Clark gave each of the 25 students 5 sheets of paper. So we can calculate the total number of sheets of paper by multiplying 25 by 5.
Total sheets of paper = 25 * 5 = 125 sheets of paper
