Answer:
Following are the solution to the given points:
Step-by-step explanation:

Each player's offer divided by the total number of players calculates the fair share
Ann's fair share 
Bob's fair share
Carol's fair share 
Denis's fair share 
Because Bob has the highest bid, that receives in the business.
Payments:
Ann
paid by estate
Bob
owes estate
Carol
paid by estate
Denis
paid by estate
Surplus
Splitting the equally among the four players. therefore one of the each receives:

The final settlement of the Ann receives:

In this questions, there are a few functions with more/less than and equal to symbol.
1. Answer: f(x)= 3
f(x)= 2<x ≤3
The x is [more than 2] and [less than 3] or [equal to 3]. The number that will fulfill the condition would be only 3 since 3 is [more than 2] and [equal to 3].
2. f(x)= 1
f(x)= 0<x ≤1
The x is [more than 0] and [less than 1] or [equal to 1]. The number that will fulfill the condition would be only 1 since 1 is [more than 0] and [equal to 1].
3. f(x)= x
f(x)= 1≤x ≤2
The x is [more than 1] or [equal to 1] and [less than 2] or [equal to 2]. The number that will fulfill the condition would be
1, since 1 is [equal to 1] and [less than 2]
2, since 2 is [more than 1] and [equal to 2]
The graph that follow the value would be: f(x)= x
4. Answer: f(x)= 4
f(x)= 3<x ≤4
The x is [more than 3] and [less than 4] or [equal to 4]. The number that will fulfill the condition would be only 4 since 4 is [more than 3] and [equal to 4].
