The line graph shows the number of blouses sold by a shop from September to February in 2014.
- What was the average number of blouses sold per month from September to February in 2014?
- The total number of blouses sold for the same period from September to February in 2013 was 700. Find the percentage decrease in the total number of blouses sold for the same period from 2013 to 2014
(a)
Total blouses sold from September to February in 2014
= 42 + 35 + 25 + 69 + 67 + 56
= 294
Average blouses sold from September to February in 2014
= 294 ÷ 6
= 49
(b)
Decrease in the number of blouses sold
= 700 - 294
= 406
Percentage decrease in the total number of blouses sold from 2013 to 2014
=
406700 x 100%
=
2950x 100%
= 58%
Answer(s): (a) 49; (b) 58%
