Question 343430
<font face="Garamond" size="+2">


The trick to this one is to consider the 4th test worth 200 points to be a 4th and 5th test, each worth 100 points.


In order to have an 80% average, you need 5 times 80 equals 400 total points.  You already have 83 + 84 + 98 = 265 points, so how many points out of the total 200 available on the 4th exam do you need to make at least 400 total?
