Answer 1

n=r/p-c/p

Step-by-step explanation:

Multiply to remove the variable from the denominator.

n=r/p-c/p

Answer 2

Answer:

$n = \frac{r - c}{P}$

I think.

Step-by-step explanation:

$P = \frac{r - c}{n} \\ (n)P = \frac{r - c}{n}(n) \\ Pn = r - c \\ \frac{Pn}{P} = \frac{r - c}{P} \\ n = \frac{r - c}{P}$
