Which equation represents the number of test questions in the problem below?
A test is worth 50 points. Multiple-choice questions are worth 1 point, and
short-answer questions are worth 3 points. If the test has 20 questions, how

B. m + 2s = 20
C. m + s = 20
D. m. s= 20

Option C. is the correct choice.

Step-by-step explanation:
