Question 1005761: Emily's gold is six weeks is to earn a grade of at least 95 in her English one honors class her grade will be determined by the average of four test grades she has earned a 92 a 100 and a 98 on her first three tests what is the minimum grade that she can make on her fourth test and attain her goal Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! To attain a 95 average of four tests, she would need to total
4 * 95 = 380 points total.
So far she has earned 92+98+100 = 290 points
Thus she needs 380-290 at least 90 points...
We could also write
(290 + x)/4 >= 95
which leads to the same
x >= 90
conclusion...
