The line graph shows the number of blazers sold by a shop from August to January in 2013.
- What was the average number of blazers sold per month from August to January in 2013?
- The total number of blazers sold for the same period from August to January in 2012 was 750. Find the percentage decrease in the total number of blazers sold for the same period from 2012 to 2013
(a)
Total blazers sold from August to January in 2013
= 74 + 67 + 80 + 25 + 53 + 61
= 360
Average blazers sold from August to January in 2013
= 360 ÷ 6
= 60
(b)
Decrease in the number of blazers sold
= 750 - 360
= 390
Percentage decrease in the total number of blazers sold from 2012 to 2013
=
390750 x 100%
=
1325x 100%
= 52%
Answer(s): (a) 60; (b) 52%
