Answer 1

Explanation:

To find the total number of text messages sent per month by the 23 million people aged 13-17 in the United States, we can multiply the average number of text messages per person (800) by the number of people (23,000,000):

Total number of text messages = 800 text messages/person/month x 23,000,000 people

Total number of text messages = 18,400,000,000 text messages/month

To express this number in scientific notation, we can move the decimal point 10 places to the left, since there are 10 digits to the right of the decimal point:

Total number of text messages = 1.84 x 10^10 text messages/month

Therefore, the total number of text messages sent per month by the 23 million people aged 13-17 in the United States is approximately 1.84 x 10^10 text messages.

Answer 2

To calculate the total number of text messages sent in the United States by this group:
23 million x 800 = 18.4 billion

To express this answer in scientific notation:
18.4 billion = 1.84 x 10^10

Therefore, approximately 1.84 x 10^10 text messages were sent in the United States per month by this group.
