Answer :
Final answer:
The mathematics problem requires setting up equations to find the relationship between the counts of elevens and twelves in a given collection, under four different scenarios.
Explanation:
The question involves a collection of numbers, specifically elevens and twelves. Each of the scenarios a) to d) describes a different relationship between the count of elevens and twelves.
To further understand each scenario, one would set up an equation for each and solve for the quantities of elevens and twelves. This exercise demonstrates the use of basic algebra to relate various quantities based on the provided conditions.
