Brian has scores of 88, 95 on his first two math tests, he wants to have an average score at least 90 points.
There are total three tests, what score must Brian get on his third test to have an overall average of 90?
Test 1: 88
Test 2: 95
Test 3: ___
Analysis: To achieve an average of 90 in three tests, Brian needs to
have total score 90+90+90=270, he already has two scores,
thus it is up to YOU to figure out what Brian must score in
test 3 to reach his goal?
Solution : 87.

My goal is to forget as much math as life will let me.
I respect your life choice, Alice!
He will need to score 87 on the third test.
3 divided into 270 = 90
