Question

There are n musicians in a marching band. All play either a drum or a brass instrument. If p represents the fraction of musicians playing drums, how many play a brass instrument?

Answer 1

Answer:

I think you 27 but give the picture thank you

Answer 2

Answer:

B ) pn - 1

Step-by-step explanation:

Through reading the question you get two variables being:

N musicians ( number of total musicians)

P Drums (number of musicians who play drums)

-------------------------------------------------------------------------------------

In order to find the answer, you would need to imagine how you would get the answer using numbers being the musicians who play drums (pn) subtracted by the number of musicians who don't play drums (-1).

Drum Musicians minus (-) the amount of non-drum playing musicians.

This would get the total amount of bass-playing musicians.
