I assume you are looking for the formally correct way to model this. Here it is: enter image description here

If less formality is sufficient, you could skip the decision input flows and simply assume that the guards have access to any objects in the scope of the activity. Then one decision node is sufficient with a guard [profit=low AND not order.customer.regular Customer].
