Here are the problems:
1.) Jenny got 50, 60, 70,80, and 90 on her 5 tests, respectively. What is her average score of the 5 tests?
Solution:
Average(mean)= Sum of terms/ number of terms
 Average(mean) = (50 + 60 + 70 + 80 + 90) / 5
 Average(mean) = 350 / 5
Average(mean) = 70
Therefore, Jenny's average on the 5 tests is 70.
2.) Jeline's points on a computer game are 5, 6,7, 8, and 9 on the 5 stages, respectively. What is her average points on the 5 stages.
Average(mean)=Sum of terms/ number of terms
Average(mean)=(5 + 6 + 7 + 8 +9)/5
Average(mean)=35/5
Average(mean)=7
Therefore, Jeline's average on the 5 stages of her computer game is 7.
