---------
Points you have:: 66+62+78 = 206
Points you need to have:: 5*74 = 370
-----
Ans:: Points you need on last 2 tests 370-206 = 164

To average 74 over 5 tests. the sum of your grades must be 5(74)=370
The sum of your current grades is 66+62+78=206 so you need 370-206=164 points
You need an average of 82 on each of the next 2 tests, or a sum of 164 points on both tests. Good luck!
