The line graph shows the number of blazers sold by a shop from September to February in 2011.
- What was the average number of blazers sold per month from September to February in 2011?
- The total number of blazers sold for the same period from September to February in 2010 was 750. Find the percentage decrease in the total number of blazers sold for the same period from 2010 to 2011
(a)
Total blazers sold from September to February in 2011
= 49 + 77 + 25 + 69 + 45 + 41
= 306
Average blazers sold from September to February in 2011
= 306 ÷ 6
= 51
(b)
Decrease in the number of blazers sold
= 750 - 306
= 444
Percentage decrease in the total number of blazers sold from 2010 to 2011
=
444750 x 100%
=
74125x 100%
= 59.2%
Answer(s): (a) 51; (b) 59.2%
