The line graph shows the number of jumpsuits sold by a shop from December to May in 2017.
- What was the average number of jumpsuits sold per month from December to May in 2017?
- The total number of jumpsuits sold for the same period from December to May in 2016 was 1000. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2016 to 2017
(a)
Total jumpsuits sold from December to May in 2017
= 61 + 92 + 54 + 61 + 55 + 61
= 384
Average jumpsuits sold from December to May in 2017
= 384 ÷ 6
= 64
(b)
Decrease in the number of jumpsuits sold
= 1000 - 384
= 616
Percentage decrease in the total number of jumpsuits sold from 2016 to 2017
=
6161000 x 100%
=
77125x 100%
= 61.6%
Answer(s): (a) 64; (b) 61.6%
