Marcos cell phone company charges $35 for phone service plus $0.50 for each text message. How many text messages did Marco send in a month if his bill was $58 write an equation that represents this situation

Let x be the number of text messages Marcos sent in a month.

The cost for phone service is $35.
The cost for text messages is $0.50 per message, so the cost for x text messages is 0.5x.

The total cost is $58.
So, $35 + 0.5x = $58.

The equation that represents this situation is:
35 + 0.5x = 58.
