Final answer:
The items with derived demand are the steam machine used for placing logos on shirts and the seamstress, as their demand is dependent on the final products they contribute to creating.
Step-by-step explanation:
Derived demand refers to the demand for a good or service that arises from the demand for another good or service. For example, the steel demand is derived from the demand for cars, as steel is a direct input in car manufacturing. In the same vein, the demand for labor, such as a seamstress, is derived from the demand for the final products they help to produce, like clothing.
In your case, the examples presented that have derived demand are:
- A steam machine that puts the logo on the shirt - because its demand is dependent on the demand for logo-printed shirts.
- A seamstress - because her demand is dependent on the need for sewn garments or modifications.
The sweatshirt with your college logo does not have derived demand; instead, it represents a final consumer product whose demand is based on consumer preferences and university affiliations.
