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 61, how many questions did Student A answer correctly?  Select the correct option:  A) 55  B) 60  C) 73  D) 81  E) 87
let the number of correct responses be x   then the number of incorrect responses =100-x   according to question   x-2(100-x)=61 (subtracting twice of incorrect from correct)   3x=261   x=87   ANSW87R:87
