If Raphael's boss is interested in a graphical representation of the relationship between the price and quantity of televisions demanded, you would advise your coworker to construct
a) a demand curve
b) a demand schedule
c) the law of demand
using the data provided. However, if Rina's boss is more interested in the detailed numbers used to construct this visual representation, you would instead advise your coworker that
a) a demand curve
b) a demand schedule
c) the law of demand
would be more appropriate.

A demand curve is a graphical presentation indicating the connection between the price of a product, for example Television, and the quantity demanded for that product at a specific price.

On the other hand, a demand schedule is a table presentation of detailed data or numbers of the price-quantity demanded relationship for a product.

Hence, the right answer are:

1. a demand curve

2. a demand schedule
