The line graph shows the number of blazers sold by a shop from October to March in 2016.
- What was the average number of blazers sold per month from October to March in 2016?
- The total number of blazers sold for the same period from October to March in 2015 was 600. Find the percentage decrease in the total number of blazers sold for the same period from 2015 to 2016
(a)
Total blazers sold from October to March in 2016
= 94 + 68 + 87 + 91 + 32 + 30
= 402
Average blazers sold from October to March in 2016
= 402 ÷ 6
= 67
(b)
Decrease in the number of blazers sold
= 600 - 402
= 198
Percentage decrease in the total number of blazers sold from 2015 to 2016
=
198600 x 100%
=
33100x 100%
= 33%
Answer(s): (a) 67; (b) 33%
