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
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
