Deven Blanchard · Answer 1

Average cost per year = 400 + 180/x

Step-by-step explanation:

Using the formula y=mx+b

We know that b is the y intercept or initial value. That would be the start up costs

m is the slope on costs each time x increases, that would be 400 per year

Costs = 400x + 180

To find the average cost per year, we need to divide by x

Average cost per year = (400x + 180) / x

= 400 + 180/x

answer to this question is f (x) = (180 + 400x) / x
