Explanation:

Giving the following information:

Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each.

To calculate the number of text messages, we need to use the following formula:

Total cost= 39 + 0.15x

x= number of text messages

55.05= 39 + 0.15x

16.05= 0.15x

107= x

Luis incurred 107 extra text messages.
