The line graph shows the number of jackets sold by a shop from April to September in 2014.
- What was the average number of jackets sold per month from April to September in 2014?
- The total number of jackets sold for the same period from April to September in 2013 was 720. Find the percentage decrease in the total number of jackets sold for the same period from 2013 to 2014
(a)
Total jackets sold from April to September in 2014
= 33 + 35 + 60 + 94 + 53 + 85
= 360
Average jackets sold from April to September in 2014
= 360 ÷ 6
= 60
(b)
Decrease in the number of jackets sold
= 720 - 360
= 360
Percentage decrease in the total number of jackets sold from 2013 to 2014
=
360720 x 100%
=
12x 100%
= 50%
Answer(s): (a) 60; (b) 50%
