Question

Can someone help me with this please :)

Answer 1

`n = (r - c)/(P)`

I think.

Explanation:

`P = (r - c)/(n) \\ (n)P = (r - c)/(n)(n) \\ Pn = r - c \\ (Pn)/(P) = (r - c)/(P) \\ n = (r - c)/(P)`

Answer 2

n=r/p-c/p

Explanation:

Multiply to remove the variable from the denominator.

n=r/p-c/p
