\frac{b(2c-r)}{(x-r)}

\frac{2x(c-r)}{(b-r)}

\frac{x(2c-r)}{(b-r)}

\frac{2b(c-r)}{(x-r)}

\frac{2(xc-r)}{(x-r)}

Let "N" be the required answer.,

(x - N)r + Nb = 2xc

xr - Nr + Nb = 2xc

N(b - r) = x(2c - r)

N = \frac{x(2c-r)}{(b-r)}

Answer is C

process of elimination + intuition :)
x and r are not of the same nature (cost in dollar and total umbrellas) => eliminate A,D,E
now, with some intuition, if retail price is less than cost, B would be negative => eliminate B
Answer is C

Could anybody try smart numbers on this one? I'm having a tough time coming up with the solution

Thanks!

Good approach, but still I don´t understand how to choose between B and C.
