The Number of text messages sent in a month is 1.68 × 
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 ×
× 800
= 168 ×
= 1.68 ×

Answer :
The Number of text messages that is sent in a month is 1.68 × 
This means that it's 12 times f, then add that by 24. This f is a variable. It could be any number. First, try to find out what f equals. Then use that to find the answer.
Answer:
28.8
Step-by-step explanation:

5x+36=180 subtract 36 from both sides
5x=144 divide both sides by 5 to isolate the variable
x=28.8
