Danielle’s text messaging plan costs 7$ for the first 700 messages and 30 cents for each additional text message. If she owes 18.40$ for text messaging in the month of October, how many text messages did she send that month?

Respuesta :

Answer:

738 messages

Step-by-step explanation:

Use the given information to set up an equation. 7 is constant and 0.3 per message, with a total of 18.40.

0.3x + 7 = 18.4

Now solve for x

0.3x = 11.4

x = 38

She sent 38 messages over the standard 700, meaning she sent a total of 738 messages in the month of October
