Answer:
(a)$29.95
(b)A
Step-by-step explanation:
The cost, in dollars, of producing x cellphone cases is given by:

We are required to evaluate: 


The value calculated above represents the additional cost to produce one more item after making 250 items.
Since it’s perpendicular tu have to flip the slope and change the sing which in this case would be -1/5
Then you put the equation together:
y-7=-1/5(x-5)
Distribute:
y-7=-1/5x+1
Add the 7 to both sides of the equation:
y-7=-1/5x+1
+7 +7
And the final answer is: y=-1/5+8
The x-intercept is 8 because it passes through the horizontal line (x) at point 8.
The y-intercept is -4 because it passes through the vertical line a (y) at point -4.
The correct answer is B.
Hope this helps!
