Step 1
The average cost function can be found by dividing the total cost by the number of items produced. In this case, the total cost function is given by x - 13 + 121x. Show more…

The cost (in dollars) of producing x units of a certain commodity is C(x) = 4,280 + 13x + 0.03x2. Please find the average rate of change with respect to x when the production level is changed from x = 106 to x = 116.

Suppose that the average yearly cost per item for producing $x$ items of a business product is $\bar{C}(x)=10+\frac{100}{x} .$ If the current production is $x=10$ and production is increasing at a rate of 2 items per year, find the rate of change of the average cost.
