On Juan's most recent phone bill he was charged a total of $16.50 for text messages. For how many text messages in total was Juan charged on this bill?

Answer:

365 messages

Step-by-step explanation:

16.5 = 10 + .10(x - 300)

6.5 = .10x - 30

36.5 = .10x

x = 365

300+65=365 text messages in total

365 text messages=$16.50

Step-by-step explanation:

6.50/0.10=65
