The line graph shows the number of zoo tickets sold from Tuesday to Saturday.
- What is the difference between the highest and the lowest number of zoo 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 zoo tickets sold = 4800 (Tuesday)
Lowest number of zoo tickets sold = 1400 (Thursday)
Difference between the highest and the lowest number of zoo tickets sold from from Tuesday to Saturday
= 4800 - 1400
= 3400
(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 zoo tickets sold from Tuesday to Wednesday
= 4800 - 2300
= 2500
Decrease in the number of zoo tickets sold from Wednesday to Thursday
= 2300 - 1400
= 900
Increase in the number of zoo tickets sold from Thursday to Friday
= 3300 - 1400
= 1900
Increase in the number of zoo tickets sold from Friday to Saturday
= 3500 - 3300
= 200
Answer(s): (a) 3400; (b) Thu to Fri
