Derive the AVC function?
Derive the MC function?
How much is AVC at an output of 10 units?
At what output level does AVC reach a minimum?
At what output level does MC reach a minimum?
Illustrate with AVC-MC diagram
a. The given total cost function is:
The variable cost function is the part of the total cost function that depends on the quantity produced:
Average variable cost function is derived by dividing the variable cost function by quantity:
b. The marginal cost function is derived by differentiating the total cost function with respect to quantity:
c. Average variable cost at 10 units of output is:
d. In order to minimize AVC, the following problem is solved:
Solving the problem:
Hence, AVC is minimized at quantity level of 2 units.
e. In order to minimize MC, the following problem is solved:
Solving the problem:
Hence, MC is minimized at quantity level of 4/3 units.
e. Plotting the MC and AVC functions:
The red curve is the MC curve and the blue curve is the AVC curve.
