It is (0,0) there ya go :)
Is there any choices for it
The graph would be similar to a Sin or Cos graph with a vertical shift. As the music gets louder the graph will go up and as the music and crowd become quieter, the graph will go down. Going up and down until the end of the concert where it will be 0.
Also side note, are you by chance in Trig 01 Summer course? If so, I am in the same class haha.
The answer is 20p. P represents the number of boxes she buys and 20 is how many pens are in each box.
