Answer:
Step-by-step explanation:
First find the rate of change or slope denoted as m
m=(y2-y1)(x2-x1) we can find the slope with any two points.
m=(35000-25000)/(600-200)
m=10000/400
m=25
Now that we know the slope we can find the y intercept or original cost
C(n)=25n+b, using any point we can solve for b, I’ll use (200, 25000)
25000=25(200)+b
25000=5000+b
b=20000 so now we know the complete equation.
C(n)=25n+20000
Answer C.
