a.27

b.54

c.216

Step-by-step explanation:

So we start by dividing 135 by 5, getting 27, which is the answer for the first problem, then you double it to get the answer for the second, which is 54, then you add the three number together 27+54+135=216

Aand c are not warning signs that the process is out of control. b is a sign that the process is out of control, the reason being that there should be points above and below the center line if the process is under control.
