Question

PLEASE EXPLAIN HOW

Answer 1

test 1=74
test 2=74
test 3=74
test 4=74
test 5=64

average of all 5 is 72.

average of first 4 is 74.

just have to find a # divisible by 5 that equals 72 when divided by 5

Then find a # divisible by 4 that equals 74 when divided by 4

take the difference, theres your answer.

Answer 2

total of his 5 games = 5(72) = 360
total of his top 4 games = 4(74) = 296
lowest game = 360-296 = 64
