Answer:
-2
Step-by-step explanation:
The computation of net change from the beginning of Tuesday to the end of Monday is shown below:-
The change at the last of Tuesday
Change = Restock - Sales
= 6 - 5
= 1
Here it indicates that the number of bags is rise by 1
The change at the last of Wednesday
Change = Restock - Sales
= 12 - 8
= 4
Here it indicates that the number of bags is rise by 4
The change at the last of Thursday
Change = Restock - Sales
= 12 - 2
= 10
Here it indicates that the number of bags is rise by 10
The change at the last of Friday
Change = Restock - Sales
= 18 - 19
= -1
Here it indicates that the number of bags is fall by -1
The change at the last of Saturday
Change = Restock - Sales
= 24 - 22
= 2
Here it indicates that the number of bags is rise by 2
The change at the last of Sunday
Change = Restock - Sales
= 0 - 15
= -15
Here it indicates that the number of bags is fall by -15
The change at the last of Monday
Change = Restock - Sales
= 0 - 3
= -3
Here it indicates that the number of bags is fall by -3
According to the given situation, it is equivalent the algebraic sum of every change
So,
Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)
Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)
Simplifying: 17 - 19 = -2
