Question

There were 816 people at a concert when a band started playing. After each song, only half of the people stayed to hear the next song. How many people were left at the concert after x songs? Write a function to represent this scenario.

Answer 1

the function for this is f(x)=816(1/2)^x

Explanation:

just took it

Answer 2

Total number of people = 816
after 1 song = 816/2 people remained
after 2 songs = 816/4 people remained
after 3 songs = 816/8 people remained
after x songs = 816/x*2 people remained

People that remained = 816/2x
where x is the number of songs

Simplified = 408/x
