Answer:
The net change is -2
Step-by-step explanation:
No. of bags Tue Wed Thu Fri Sat Sun Mon
Sales 5 8 2 19 22 15 3
Restock 6 12 12 18 24 0 0
Change in bags = Restock - Sales
Change in Tuesday = 6-5 = 1
Change in Wednesday = 12-8 = 4
Change in Thursday = 12-2 = 10
Change in Friday = 18-19 = -1
Change in Saturday = 24-22 = 2
Change in Sunday = 0-15 = -15
Change in Monday = 0-3 = -3
Net change = 1+4+10+(-1)+2+(-15)+(-3)=-2
Hence The net change is -2
