The line graph shows the number of dresses sold by a shop from March to August in 2014.
- What was the average number of dresses sold per month from March to August in 2014?
- The total number of dresses sold for the same period from March to August in 2013 was 1000. Find the percentage decrease in the total number of dresses sold for the same period from 2013 to 2014
(a)
Total dresses sold from March to August in 2014
= 69 + 38 + 82 + 81 + 78 + 54
= 402
Average dresses sold from March to August in 2014
= 402 ÷ 6
= 67
(b)
Decrease in the number of dresses sold
= 1000 - 402
= 598
Percentage decrease in the total number of dresses sold from 2013 to 2014
=
5981000 x 100%
=
299500x 100%
= 59.8%
Answer(s): (a) 67; (b) 59.8%
