Answer:
The correct answer is: is relatively inelastic because there are very few substitutes for lightbulbs.
Step-by-step explanation:
The demand for unit elasticity is an intermediate situation between an elastic and other inelastic demand curve, so that the price elasticity is equal to one, which means that in the face of variations in price, the total ingrowth (price per cantidad), if it decides, if the price increases, the demanded cantidad will diminish in an amount such that the previous and the present in the same ones. The same would occur in the case that the price had fallen, the song would increase so much that the ingrowth remained constant.
