Answer: he sent 574 text messages that month

Step-by-step explanation:

Let x represent the number additional text messages that he sent that month.

If his text messaging complain cost $9 for the first 550 text messages and .20 for additional text messages, it means that the total cost of sending x text messages for a month would be

9 + 0.2(x - 550)

If Tj owes $13.80 for text messaging in the month of March, it means that

9 + 0.2(x - 550) = 13.8

0.2x - 110 = 13.8 - 9

0.2x = 13.8 - 9 + 110

0.2x = 114.8

x = 118.8/0.2

x = 574
