Answer:
The number -2 shows the total change in amount of cookies. The negative sign signifies the decrease in the number.
Step-by-step explanation:
Total cookies Quon has = 15
Cookies eaten in the afternoon = 1
Cookies eaten in the evening = 1
So, total number of cookies consumed = [tex]1+1 =2[/tex]
Cookies left with Quon = [tex]15-2=13[/tex]
So, the number -2 shows the total change in amount of cookies. The negative sign signifies the decrease in the number.
