Firms A and B have the same fixed costs in producing widgets. However, firm A charges 15% more than firm B for a widget while its variable costs per widget are
12% lower than those of B. If firm A sells a widget for 35% above its variable costs, the break-even point for B is ________ times higher than that for A.

A. B. C. D.B
The break-even quantity, Q, is given by Q = FC/(P - V), where FC = total fixed costs, P = average sale price per unit and V = average variable cost per unit.
You're given that FCA = FCB, PA = 1.35VA, PA = 1.15PB and VA = 0.88VB. Therefore, PB = (1.35/1.15)VA = 1.174VA and VB = (1/0.88)VA = 1.136V
A.
This gives QA/QB = FC(PA-VA)/FC(PB-VB) = (PB - VB)/(PA - VA) = (1.174 - 1.136)/(1.35 - 1) = 0.109.
Thus, the break-even point for B is (1/0.109) = 9.21 times that for A.
