Answer:


30 + 0.05x < 60

The number of texts she can have is less than 600.

Explanation:

Total monthly charge

30 + 0.05 for each text.

So, for x tests, the charge is:


C(x) = 30 + 0.05x

Write an inequality to represent the # of texts she can have?

It has to be under 60, so:


C(x) < 60


30 + 0.05x < 60

The solution is:


0.05x < 30


x < (30)/(0.05)


x < 600

The number of texts she can have is less than 600.
