Texting plan charges $10 per month plus $0.10 per text message.
How many text messages must you send per month, in order for average cost per text to be $0.15
~~~~~~~~~~~~~~~
Write an equation as you read the problem
= 0.15
Then solve it and find n, the number of the text messages
10.00 + 0.10n = 0.15n
10.00 = 0.15n - 0.10n
10.00 = (0.15-0.10)*n
10.00 = 0.05n
n = = 200 text messages. ANSWER
Solved.

Comment from student : Thank you for your quick answer but I don't understand how you got n=10/0.05 or 200.
Can you please explain. Thank you
My response. From your comment, it seems to me that you are in wrong class,
if you do not understand so simple elementary issues.
