Final answer:
The number of nonnegative variables in (4.1.2) equals the number of constraints in (4.1.1), representing the limitations and resources in a budget constraint.
Step-by-step explanation:
The question refers to a budget constraint, which is a concept in economics. The number of nonnegative variables in (4.1.2) represents the number of goods or resources that can be consumed, while the number of constraints in (4.1.1) represents the limitations or restrictions on the consumption of those resources.
In the given context, the price was to be set using (4.1.2) for each limited resource in (4.1.1), indicating that the budget constraint determines how much of each resource can be obtained with the available budget.
