Question

Megan's text messaging plan costs $15 for the first 600 messages and 5¢ for each additional text message. If she owes $24.60 for text messaging in the month of October, how many text messages did she send that month?

Answer 1

create an equation where x equals extra messages

15 + .05X = 24.60

.05x = 9.60

x=192

So she sent 192 EXTRA messages. Add this to the original 600 and you get 792 messages
