- 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 = 4100 (Thursday)
Lowest number of concert tickets sold = 1000 (Tuesday)
Difference between the highest and the lowest number of concert tickets sold from from Monday to Friday
= 4100 - 1000

Between Tuesday to Wednesday, the number of tickets sold increased the greatest.
To show:
Decrease in the number of concert tickets sold from Monday to Tuesday
= 3200 - 1000

Increase in the number of concert tickets sold from Tuesday to Wednesday
= 3200 - 1000
= 2200
Increase in the number of concert tickets sold from Wednesday to Thursday
= 4100 - 3200
= 900
Decrease in the number of concert tickets sold from Thursday to Friday
= 4100 - 2400
= 1700
Answer(s): (a) 3100; (b) Tue to Wed
