Question

If fixed cost is $8,000, variable cost is $5,000 at an output of 2 and $9,000 at an output of 3, how much is marginal cost at an output of 3?
Can someone show me how to do the formula step by step?

(13k/2)-(17k/3)= X

6.5k - 5.667k = X

X = .833k

answer is =$4,000

The change in cost from 2 to 3 units of output would be the marginal cost of unit 3. The difference is the difference in variable costs, $9,000 minus $5,000.

Thanks, Anonymous...Although I understand the concept I need to actually see the formula. I am a visual kindda person.
