Si del modelo Costo (C)-Ingreso(I)-Utilidad(U) se conoce que \( U(140)=0 \) y \( U(0)=-25000 \) se puede asegurar que: El costo fijo es -25000 unidades monetarias Fabricando y vendiendo 140 unidades se logra equilibrio en el mercado. El punto de equilibrio Costo_Ingreso es ( \( 140,-25000 \) ) Fabricando y vendiendo menos de 140 unidades se obtienen ganancias.
