Final answer:
Option c) is correct because it directly states that the Seattle price will become double the Port Townsend price. This fits with the principle of ratios, where three times the price of one location directly results in double the price in the other location as stated in the option.
Step-by-step explanation:
To determine when the Seattle sales price will be double the Port Townsend sales price, let's start with the available options, and use the concept of ratios and proportions. We have these scenarios:
- a) If the Seattle price is half of the Port Townsend price, it will become four times its original value.
- b) If the Seattle price is four times the Port Townsend price, it will become sixteen times its original value.
- c) If the Seattle price is three times the Port Townsend price, it will become double its original value.
- d) If the Seattle price is equal to the Port Townsend price, it will remain unchanged.
From these options, c) is the correct one, as it directly states that the Seattle price will be double the Port Townsend price. In other words, for every $1 in Port Townsend, Seattle will have $2. This is already given as the scenario. Options a, b, and d provide results that do not indicate the Seattle price being double the Port Townsend price.
