In a game, a player starts with 100 points. Each question has two parts and an incorrect answer for both parts results in a loss of 1 point. The student loses one-half of a point for getting only one part of the question correct. At the end of a 25 question round, the player has 82.5 points. What TWO equations and solutions represent x missed points? Answer choices:
A. 100−x=82.5

The player misses 17.5 points.

C. 82.5−x=100
The player misses 18.5 points.

D. x−100=−82.5
The player gets 7.5 points.

E. x−100=−82.5
