The Number of text messages sent in a month is 1.68 × 10^{(-8)}

Step-by-step explanation:

Step 1 :

Total number of teenagers in United States = 21 million

Average text messages sent per month = 800

We need to find the number of text messages sent each month

Step 2 :

The number of text messages in a month can be computed by taking the product of the total number of teenagers and average messages sent per month

Number of text messages that is sent in a month = 21 million ×  800

                                                                      = 21 × 10^{6} × 800

                                                                     = 168  × 10^{6} = 1.68 × 10^{(-8)}

qwelly [4]
Short answer: No
