The cost will be same for one session. The cost will be $128.
Step-by-step explanation:
Given, 
Initial consultation charges for Plan One = $36 
Per session fee = $92
Let, 
x be the number of sessions.
O(x) = 92x+36
Initial consultation charges for Plan Two = $86 
Per session fee = $42
T(x) = 42x+86 
For same cost; 
O(x) = T(x) 

Dividing both sides by 50 

Putting x=1 in T(x) 

Putting x=1 in O(x) 

The cost will be same for one session. The cost will be $128.
