Explanation:

The demand schedule is a table that shows the relationship between price and quantity demanded of a consumer. It can be seen that the higher the price, the lower the quantity demanded. This is in line with the law of demand.

The demand curve is a curve that shows the relationship between price and quantity demanded. The demand curve is negatively sloped because the higher the price, the lower the quantity demanded. This is in line with the law of demand.

According to the law of demand, the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded.

Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.

Consumer surplus = willingness to pay – price of the good

the price of the good is $4 and when price is $7, he would purchase a bottle and when it is $5, he would buy a second bottle.

Thus, he would buy 2 bottles when the price is $4
