Need to keep cell bill under 60.,monthly charge is 30. And texts are 0.05 each. Write an inequality to represent the # of texts

nignag [31]

Answer:

$30 + 0.05x < 60$

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

Step-by-step 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:

$0.05x < 30$

$x < \frac{30}{0.05}$

$x < 600$

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