(a)
Highest number of concert tickets sold = 4800 (Monday)
Lowest number of concert tickets sold = 1100 (Wednesday)
Difference between the highest and the lowest number of concert tickets sold from from Monday to Friday

Between Wednesday to Thursday, the number of tickets sold increased the greatest.
To show:
Decrease in the number of concert tickets sold from Monday to Tuesday
= 4800 - 2700

Decrease in the number of concert tickets sold from Tuesday to Wednesday
= 2700 - 1100
= 1600
Increase in the number of concert tickets sold from Wednesday to Thursday
= 2100 - 1100
= 1000
Increase in the number of concert tickets sold from Thursday to Friday
= 2200 - 2100
= 100
