Question

Solve the formula for the variable given.
P = r-c/n solve for c. (business)

I have worked this problem so many times I'm getting confused. please help.

Thanking you in advance

Answer 1

Basically, we want to isolate c. That means we find c in terms of other stuff. So, get rid of everything else and solve for c.

P = r-c/n (This is kinda unclear - is the divided sign under the c or under the r-c, if so write as (r-c)/n, but in this problem I will assume it is P = r - (c/n))

Anyways, we minus the r from both sides to get

P-r = -c/n

Then, we multiply both sides by n to get
n (P-r) = -c

We multiply both sides by -1 to get rid of the negative sign of the c.

-n(P-r) = c

We can write this as either

c= -n(P-r)

or c = nr- PN
