The line graph shows the number of jumpsuits sold by a shop from December to May in 2012.
- What was the average number of jumpsuits sold per month from December to May in 2012?
- The total number of jumpsuits sold for the same period from December to May in 2011 was 700. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2011 to 2012
(a)
Total jumpsuits sold from December to May in 2012
= 69 + 42 + 96 + 64 + 88 + 61
= 420
Average jumpsuits sold from December to May in 2012
= 420 ÷ 6
= 70
(b)
Decrease in the number of jumpsuits sold
= 700 - 420
= 280
Percentage decrease in the total number of jumpsuits sold from 2011 to 2012
=
280700 x 100%
=
25x 100%
= 40%
Answer(s): (a) 70; (b) 40%
