The line graph shows the number of blazers sold by a shop from May to October in 2017.
- What was the average number of blazers sold per month from May to October in 2017?
- The total number of blazers sold for the same period from May to October in 2016 was 960. Find the percentage decrease in the total number of blazers sold for the same period from 2016 to 2017
(a)
Total blazers sold from May to October in 2017
= 22 + 32 + 96 + 81 + 38 + 67
= 336
Average blazers sold from May to October in 2017
= 336 ÷ 6
= 56
(b)
Decrease in the number of blazers sold
= 960 - 336
= 624
Percentage decrease in the total number of blazers sold from 2016 to 2017
=
624960 x 100%
=
1320x 100%
= 65%
Answer(s): (a) 56; (b) 65%
