a. y= 20x + 10

b y= 12x+4

c. y=10x+20

note- explain how you got the anwser

  C.  y=10x+20

Step-by-step explanation:

Madison worked 2 more hours the first week than the second week, and was paid $20 more. Thus, her hourly pay must be $20/2 = $10.

The only equation that multiplies hours by 10 is that of selection C.

Check

Filling in x=10, we get y=120, corresponding to Madison's first week's pay.

Filling in x=8, we get y=100, corresponding to Madison's second week's pay.

The equation we chose (y=10x+20) represents Madison's pay for working x hours.
