Final answer:
The information given does not specify whether the number of people touring the candy factory is constant, increasing, or decreasing over a week's 3-period; hence, the correct answer is that it is not provided in the question.
Step-by-step explanation:
The question does not provide enough information to determine if the number of people who toured the candy factory over a week's 3-period is either a constant, increasing, or decreasing value. Without additional data or context, such as the number of visitors each day or patterns in the visitation rates, it is impossible to ascertain the trend in the number of visitors. Therefore, the correct answer is (b) Not provided in the question.
In terms of economic supply and demand, a situation described with constant, increasing, or decreasing costs would relate to how the supply and demand curves shift in response to changes in the market. For instance, if demand increases and supply meets it equally, we see a constant cost scenario where the equilibrium price remains unchanged as the quantity sold increases. If supply cannot meet the increased demand due to factors such as scarce inputs or rising wages, then we observe increasing costs and a rise in the equilibrium price. Conversely, if supply increases significantly due to technology advances or economies of scale, then we might see decreasing costs and a declining equilibrium price.
