Question

11. Morty scored an 80, 60, 20, and an 20 on his first four math

tests. What does he need to score on his fifth math test to
average an 50 overall?

Answer 1

he would need to score a 70

Explanation:

So, 80+60+20+20 = 180 and to find the average dived by the number of numbers witch is 45. to find the missing number you would need to add 180 and a number. I started at 20 then 30,40,50,60, then, 70. so 180+70 is 250 and 250/5 is 50

Answer 2

Answer: He needs to score a 20% on his last test.

Explanation:

80+60+20+20+20 = 200. 200/4 = 50
