The line graph shows the number of jumpsuits sold by a shop from September to February in 2014.
- What was the average number of jumpsuits sold per month from September to February in 2014?
- The total number of jumpsuits sold for the same period from September to February in 2013 was 804. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2013 to 2014
(a)
Total jumpsuits sold from September to February in 2014
= 100 + 83 + 60 + 33 + 45 + 81
= 402
Average jumpsuits sold from September to February in 2014
= 402 ÷ 6
= 67
(b)
Decrease in the number of jumpsuits sold
= 804 - 402
= 402
Percentage decrease in the total number of jumpsuits sold from 2013 to 2014
=
402804 x 100%
=
12x 100%
= 50%
Answer(s): (a) 67; (b) 50%
