(a)
Highest number of zoo tickets sold = 4500 (Friday)
Lowest number of zoo tickets sold = 1100 (Wednesday)

Between Wednesday to Thursday, the number of tickets sold increased the greatest.
To show:
Decrease in the number of zoo tickets sold from Tuesday to Wednesday
= 3700 - 1100

Increase in the number of zoo tickets sold from Wednesday to Thursday
= 3700 - 1100

Increase in the number of zoo tickets sold from Thursday to Friday
= 4500 - 3700
= 800
Decrease in the number of zoo tickets sold from Friday to Saturday
