how does the last equation come (red one) ??

Algebraic solution
• Equate total revenue and total cost functions and solve for Q
TR = PxQ
TC = FC + (VC x Q)
TR = TC
Px Qg = FC + VC x Qg
(P x Q)- (VC x Qg) = FC
Qg (P- VC) = FC
Qg = FC/(P- VC), or in terms of total dollar sales,
PQ = (FxP)/(P-VC) = ((FxP)/P)/((P-VC)/P) = F/((P/P)- (VC/P)) = F/(1-VC/P)
