Answer 1

Find the total score of the 4 tests:

Average of the 4 test scores = 80

Sum = average x number of test

Sum of the 4 test scores = 80 x 4 = 320

Find the total score of the 5 tests:

Average of the 5 test scores = 84

Sum = average x number of test

Sum of the 5 test scores = 5 x 84 = 420

Find the score needed for the 5th test:

5th test = 420 - 320 = 100

Answer: He needs to score 100 for the 5th test.
