Question 1046350
<font face="Times New Roman" size="+2">


Three tests that are worth 100 maximum plus one test that is worth 200 maximum is the same thing as five tests that are worth 100 each.  So you want the average of five scores to be 90.  If the average of 5 scores is at least 90, then the total of the 5 scores must be at least 5 times 90.  Add the scores that you have and subtract from 5 times 90 to get the score you need out of 200 on the last test.
