Jamie plays a trivia game. She earns 1 point for each correct answer and loses 0.25 points for each incorrect
answer. She gets 15 correct answers and 5 incorrect
answers
What is her score for the game?
A 16.25
B 13.75
C. 15
D. 14.25

 B. 13.75

First write out the equation you need to solve

1x - 0.25y = total score

Second fill in the known information

1(15) - 0.25(5) = total score

Now solve your equation

15 - 1.25 = total score

13.75 = total score

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
