Answer:
There will be
billion messages sent or received in November.
Step-by-step explanation:
Given.
Number of text messages sent or received
billion.
Increment on the very next month ![=13\%=\frac{13}{100}=0.13](https://tex.z-dn.net/?f=%3D13%5C%25%3D%5Cfrac%7B13%7D%7B100%7D%3D0.13)
Lets find what is ![13\%\ of\ 215](https://tex.z-dn.net/?f=13%5C%25%5C%20of%5C%20215)
⇒![13\%\ of\ 215](https://tex.z-dn.net/?f=13%5C%25%5C%20of%5C%20215)
⇒![0.13\times 215=27.95](https://tex.z-dn.net/?f=0.13%5Ctimes%20215%3D27.95)
So we will add this value to our previous months data.
Now
Number of text messages sent in the month of November
billion.
Rounding to the nearest tenth the answer will be
billion.
So
billion text messages were sent or received in November.
