The line graph shows the number of jackets sold by a shop from May to October in 2013.
- What was the average number of jackets sold per month from May to October in 2013?
- The total number of jackets sold for the same period from May to October in 2012 was 975. Find the percentage decrease in the total number of jackets sold for the same period from 2012 to 2013
(a)
Total jackets sold from May to October in 2013
= 54 + 79 + 87 + 79 + 69 + 22
= 390
Average jackets sold from May to October in 2013
= 390 ÷ 6
= 65
(b)
Decrease in the number of jackets sold
= 975 - 390
= 585
Percentage decrease in the total number of jackets sold from 2012 to 2013
=
585975 x 100%
=
35x 100%
= 60%
Answer(s): (a) 65; (b) 60%
