- What is the difference between the highest and the lowest number of museum tickets sold from Wednesday to Sunday?
- 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 museum tickets sold = 4900 (Saturday)
Lowest number of museum tickets sold = 1200 (Thursday)
Difference between the highest and the lowest number of museum tickets sold from from Wednesday to Sunday
= 4900 - 1200
= 3700
(b)
To find the greatest increase in the number of tickets sold, look for the steepest increasing slope.
Between Thursday to Friday, the number of tickets sold increased the greatest.
To show:
Decrease in the number of museum tickets sold from Wednesday to Thursday
= 2900 - 1200
= 3700
Increase in the number of museum tickets sold from Thursday to Friday
= 3700 - 1200
= 2500
Increase in the number of museum tickets sold from Friday to Saturday
= 4900 - 3700
= 1200
Decrease in the number of museum tickets sold from Saturday to Sunday
= 4900 - 3100
= 1800
Answer(s): (a) 3700; (b) Thu to Fri
