A teacher grades students' tests by subtracting twice the number of incorrect responses from the number of correct responses. If Student A answers each of the 100 questions on her test and receives a score of 73, how many questions did Student A answer correctly?
A. 55
B. 60
C. 73
D. 82
E. 91
The OA is E.
I get the solution to this PS question as follows,
Let the number of correct responses be = x
So the number of wrong responses = 100 - x
x - 2(100 - x) = 73
x - 200 + 2x = 73
3x = 273
x = 91
Option E.
