The following table shows the number of patients treated and the total costs for a hospital for each of the past four months:

Applying the high-low method to the above information, an equation that could be used to forecast total cost ($) from the number of patients to be treated (where x = number of patients to be treated) is:
A 22,900 + 2.40x 

B 24,300 + 2.50x 

C 25,000 + 2.50x 

D 25,500 + 2.40x
