Answer:
a family-owned restaurant
a manufacturer of cars
A company that invented a very comfortable razor
Explanation:
A family owned resturant is an example of a monpolistically competitive firm. A monpolistically competitive firm is characterised by many firms selling differentiated products. Advertising is one of the ways to attract customers to the restaurant.
A family owned farm is an example of a perfectly competitive firm. A perfectly competitive firm is characterised by many firms selling homogenous products. Thus, it won't be so necessary for a farm to advertise since its product is homogenous.
A car manufacturer exists in a monopolistic market. A monpolistically competitive firm is characterised by many firms selling differentiated products. Advertising is one of the ways to attract customers to purchase cars.
Forklifts aren't so differentiated. Therefore, there would be little need to advertise.
A manufacturer of a very comfortable razor should advertise his product to inform and attract customers. The manufacturer of a uncomfortable razor has no need to advertise.
