Answer: Jose faces a downward sloping demand.
Step-by-step explanation:
The Demand Curve in a Competitive Market is horizontal not downward sloping to represent that the firms in such a market are price takers as the demand is also equal to the price.
The horizontal nature of the demand shows that demand in such a market is perfectly elastic so if a person deviates from the market price, the quantity demanded from them changes infinitely and consumers will buy from other sellers instead.
Jose therefore cannot be facing a downward sloping demand curve in this market.
