You can put this solution on YOUR website! You are taking a computer course in which there will be four tests, each worth 100 points. You have scores of 92, 88, and 100 on the first three tests. You must make a total of 360 in order to get an A. What scores on the last test will give you an A?
-------------------------
Let "x" be the needed score.
EQUATION:
(92+88+100+x) >= 360
x+ 280 >= 360
x >= 80
-------------
You need a score of at least 80 on the 4th test.
