Let the correct answers be denoted by C.
Let the incorrect answers be denoted by I.
Given the following data;
Correct answers = 45 answers

Answer:
C: $3
Step-by-step explanation:
I think you're saying that the chips cost $4, so that's what I'm going with.
You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.
Now you can subtract 1 from 4 : 4-1= $3
Hope that helps!
Solve the system
<span>y = x + 4
y = 3x + 6
Note that both equations have been solved for y. Thus, you can set y = y, or
x+4=3x+6. Simplifying, -2 = 2x, or x = -1.
Another way to look at this would be x + 4 = 3x + 6.</span>
