Answer 2

Answer:84

Step-by-step explanation: add all the numbers together you should get a total of 395

Step 2 divide 395 by 5 = 79 that’s your average so far

Step 3 ( x the 6th test)

5• 79 + x =80 You will first multiply

6 5•79 = 395

Then 80 • 6 =480

Then subtract 480-395 = 85 is the lowest you will need to make
