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.

$\frac{2}{5}+\frac{\not2^1}{\not10_5}=\frac{2}{5}+\frac{1}{5}=\frac{2+1}{5}=\frac{3}{5}\\\\\\\\\frac{2}{5}+\frac{2}{10}=\frac{2\cdot2}{5\cdot2}+\frac{2}{10}=\frac{4}{10}+\frac{2}{10}=\frac{4+2}{10}=\frac{6}{10}=0,6$
