Question 999454
<font face="Times New Roman" size="+2">


If she wants an average of 90 on 6 tests, then the total of her scores for the 6 tests must be 6 times 90.  You can calculate the total of the first three scores and then subtract that from the overall total needed.  This is the total she will need for the last three tests.  Divide this total by 3 to get the average needed for the last three tests.
