- What is the difference between the highest and the lowest number of concert tickets sold from Tuesday to Saturday?
- Between which 2 days did the number of tickets sold increase the greatest? Give your answer in the following format. (Eg Mon to Tue)
(a)
Highest number of concert tickets sold = 4300 (Friday)
Lowest number of concert tickets sold = 1000 (Wednesday)
Difference between the highest and the lowest number of concert tickets sold from from Tuesday to Saturday
= 4300 - 1000

(b)
To find the greatest increase in the number of tickets sold, look for the steepest increasing slope.
Between Wednesday to Thursday, the number of tickets sold increased the greatest.
To show:
Decrease in the number of concert tickets sold from Tuesday to Wednesday
= 2200 - 1000
= 3300
Increase in the number of concert tickets sold from Wednesday to Thursday
= 3700 - 1000
= 2700
Increase in the number of concert tickets sold from Thursday to Friday
= 4300 - 3700
= 600
Decrease in the number of concert tickets sold from Friday to Saturday
= 4300 - 2900
= 1400
