The line graph shows the number of blazers sold by a shop from September to February in 2014.
- What was the average number of blazers sold per month from September to February in 2014?
- The total number of blazers sold for the same period from September to February in 2013 was 900. Find the percentage decrease in the total number of blazers sold for the same period from 2013 to 2014
(a)
Total blazers sold from September to February in 2014
= 22 + 48 + 54 + 67 + 75 + 58
= 324
Average blazers sold from September to February in 2014
= 324 ÷ 6
= 54
(b)
Decrease in the number of blazers sold
= 900 - 324
= 576
Percentage decrease in the total number of blazers sold from 2013 to 2014
=
576900 x 100%
=
1625x 100%
= 64%
Answer(s): (a) 54; (b) 64%
