What is the net change of how many bags are on the shelf, from the the beginning of tuesday to the end of monday?

- 2

Step-by-step explanation:

- - - - - - - - - - - T - - W - - TH - - F - - S - - S - - M

# of SALE - - - 5 - - 8 - - - 2 - - 19 - 22 - 15 - - 3

# of restock - 6 - - 12 - - 12 - - 18 - 24 - 0 - - 0

Calculating the change in shelf unit on a daily basis:

Change = difference in restock unit and the unit sold, that is, # RESTOCK - # SOLD

TUESDAY :

6 - 5 = 1

WEDNESDAY :

12 - 8 = 4

THURSDAY :

12 - 2 = 10

FRIDAY :

18 - 19 = - 1

SATURDAY :

24 - 22 = 2

SUNDAY :

0 - 15 = - 15

MONDAY :

0 - 3 = - 3

The net change equals the algebraic sum of all daily changes in shelf unit between Tuesday to Monday ;

[1 + 4 + 10 + (-1) + 2 + (-15) + (-3)]

[1 + 4 + 10 - 1 + 2 - 15 - 3]

[ 1 + 4 + 10 + 2 - 1 - 15 - 3]

= 17 - 19

= - 2

Number of bags decreased by 2

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
