Answer:
Option C. The class average will go down
Step-by-step explanation:
we know that
If Billy's paper score is equal to the class average, then the class average stay the same
If Billy's paper score is less to the class average, then the class average will go down
If Billy's paper score is greater to the class average, then the class average will go up
In this problem we have
Billy's paper score is 80%
Class average is 93%
so
80% < 93% ----> Billy's paper score is less to the class average
therefore
The class average will go down
