The line graph shows the number of jackets sold by a shop from May to October in 2015.
- What was the average number of jackets sold per month from May to October in 2015?
- The total number of jackets sold for the same period from May to October in 2014 was 976. Find the percentage decrease in the total number of jackets sold for the same period from 2014 to 2015
(a)
Total jackets sold from May to October in 2015
= 21 + 37 + 65 + 82 + 81 + 80
= 366
Average jackets sold from May to October in 2015
= 366 ÷ 6
= 61
(b)
Decrease in the number of jackets sold
= 976 - 366
= 610
Percentage decrease in the total number of jackets sold from 2014 to 2015
=
610976 x 100%
=
58x 100%
= 62.5%
Answer(s): (a) 61; (b) 62.5%
