If a company increases its production level from 100 to 150 units and the total cost rises from $1,000 to $1,200, what is the marginal cost of producing the additional 50 units?

To find the marginal cost of producing additional units, we first need to look at the change in total cost and the change in production level. In this case, the total cost increased from $1,000 to $1,200, which is a difference of $200. At the same time, the production level went up from 100 units to 150 units, which is an increase of 50 units. To find the marginal cost, we divide the change in total cost by the change in the number of units produced, so we take $200 and divide it by 50 units. This means the marginal cost of producing the additional 50 units is $4 per unit, which tells us how much it costs to make each extra unit.
