300 messages would have to be sent or received in order for the plan to cost same each month.
Step-by-step explanation:
Given, 
Cost per month = $30
Per text sent or received charges = $0.10 
Let, 
x be the number of texts sent or received.
A(x) = 0.10x+30    
A comparable plan costs = $60 per month
Text messages are unlimited.
B(x) = 60
For the two plans to cost equal;
A(x) = B(x)

Dividing both sides by 0.10

300 messages would have to be sent or received in order for the plan to cost same each month.
