Given

Danielle owes $13.80 for text messaging in the month of March.

If her text messaging plan costs $9 for the first 550 messages and 20¢ for each additional text message.

To find the number of text messages did she send that month.

Now,

Let x be the number of text messages she send that month.

Then, from the given data,

[tex]x=550+\frac{13.8-9}{0.20}[/tex]

Since 20cents is $0.20.

Then,

[tex]\begin{gathered} x=550+\frac{13.8-9}{20}\times100 \\ =550+\frac{4.8\times100}{20} \\ =550+4.8\times5 \\ =550+24 \\ =574 \end{gathered}[/tex]

Hence, the number of text messages send by her is 574.
