There are 140 people in a singing competition. The graph shows the results for the first five rounds.
Part A: 140-15x
Part B: 20 people
Part C:
There are 20 people left after the eighth round. So, 20 people compete in the ninth round.
Write an expression for the number of people after x
rounds. that is the question
I need help can someone pls answer the question ☹️
Hi, Nick, I have the same question as you! I can see the graph and did not understand how to right the expression. However, for b I got 20 people.
In each round 15 people get eliminated, the sixth round would have 50 people, and so on. Then for the multiple choice I got the first option because it relates to my answer for b.
Hope this helps!
-awesome :D
