Question

-. In Ms. Nice's class of 9 students, the average

on the last math test was a 94. A new student
recently entered the class and scored a 99 on the
exam. What is the class's new average for this
math test?

Answer 1

Answer: 94.5

Explanation:

If average of 9 students is 94, their total will be 94x 9 = 846

If the 10th student scores 99, the new total is 846 + 99 = 945

So, the new average will be

945/10 = 94.5
