Determine the cost per patient visit for each type of patient visit at the clini

Determine the cost per patient visit for each type of patient visit at the clinic. All types of visits are given in the same clinic, but about 60% of the space is used for child visits (half ill half well) and 40% for adult visits (half ill half well). Doctors and nurses traced their hours using time cards.

Does this mean if the clinic provided one additional well child visit, the total costs of the clinic would increase by the per unit cost you determined above? Why or why not?
