Answer 1

Explanation:

Not sure what the question is but...

At 4 o clock Devon + 6 people know the weather forecast

At 6 o clock the 6 people that know the weather forecast call another 6 people, making it a total of 36 people + Devon who know about the weather forecast. To find the amount of people called, subtract 36 by 6, which means 30 people were called.

At 8 o clock the 30 friends who were informed about the weather forecast each call another 6 of their friends. 6*30 is 180. So, 180 + Devon knows about the weather forecast. In total 180 + Devon knows about the weather forecast. The find the amount of people called at 8 o clock, subtract 180 by 30, so 150 people were called at 8 o clock.
