ABC Medical Clinic offers a number of specialized medical services. A review of data for the year just ended revealed variable costs of $32 per patient day; annual fixed costs of $480,000, which are incurred evenly throughout the year; and semi variable costs that displayed the following behavior at the "peak" and "valley" of activity:

January (2,400 patient days): $258,400 August (2,900 patient days): $278,900

Required:

A.Calculate the total cost for an upcoming month (2,800 patient days) if current cost behavior patterns continue. ABC uses the high-low method to analyze cost behavior.

B.There is a high probability that ABC's volume will increase in forthcoming months as patients take advantage of new scientific advances. Can the data and methodology used in part (a) for predicting the costs of 2,800 patient days be employed to estimate the costs for, say, 3,800 patient days? Why or why not?
