Final answer:
The demand curve for a product is used to determine the quantity demanded at a given price.
Step-by-step explanation:
The subject of this question is Mathematics and it is relevant to high school students.
The demand curve for a product is given by q = 17 - 2p, where p is the price of the product and q is the quantity demanded. The price of a substitute good is not mentioned in the question, so we cannot provide a specific answer. However, we can use this demand curve to determine the quantity demanded at a given price.
To solve for quantity demanded, we substitute the given price into the demand equation and solve for q. For example, if the price is $2, we substitute p = 2 into the equation: q = 17 - 2(2) = 17 - 4 = 13. Therefore, at a price of $2, the quantity demanded is 13.
