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


    %2810.00+%2B+0.10n%29%2Fn = 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 = 10.00%2F0.05 = 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.
