The following table shows the number of patients treated and the total costs for a hospital for each of the past four months:
|
Month |
Patients |
Total Cost $ |
|
1 |
5,000 |
37,500 |
|
2 |
8,400 |
45,660 |
|
3 |
8,300 |
45,050 |
|
4 |
5,900 |
39,420 |
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
