The line graph shows the number of blouses sold by a shop from May to October in 2015.
- What was the average number of blouses sold per month from May to October in 2015?
- The total number of blouses sold for the same period from May to October in 2014 was 900. Find the percentage decrease in the total number of blouses sold for the same period from 2014 to 2015
(a)
Total blouses sold from May to October in 2015
= 40 + 59 + 63 + 23 + 51 + 52
= 288
Average blouses sold from May to October in 2015
= 288 ÷ 6
= 48
(b)
Decrease in the number of blouses sold
= 900 - 288
= 612
Percentage decrease in the total number of blouses sold from 2014 to 2015
=
612900 x 100%
=
1725x 100%
= 68%
Answer(s): (a) 48; (b) 68%
