F(2) = 20(1.25)^x
f(2) = 20(1.25)^2 - plug in 2 to x
f(2) = 20(1.5625) - calculate 1.25^2
f(2) = 31.25 - simplify

<em>The least number of items to produce is 41</em>
Step-by-step explanation:
<u>Average Cost</u>
Given C(x) as the cost function to produce x items. The average cost is:

The cost function is:

And the average cost function is:

We are required to find the least number of items that can be produced so the average cost is less or equal to $21.

Adding 20x:


Swapping sides and changing the sign:

Dividing by 41:

The least number of items to produce is 41
