The line graph shows the number of blazers sold by a shop from April to September in 2014.
- What was the average number of blazers sold per month from April to September in 2014?
- The total number of blazers sold for the same period from April to September in 2013 was 960. Find the percentage decrease in the total number of blazers sold for the same period from 2013 to 2014
(a)
Total blazers sold from April to September in 2014
= 47 + 84 + 76 + 50 + 67 + 96
= 420
Average blazers sold from April to September in 2014
= 420 ÷ 6
= 70
(b)
Decrease in the number of blazers sold
= 960 - 420
= 540
Percentage decrease in the total number of blazers sold from 2013 to 2014
=
540960 x 100%
=
916x 100%
= 56.25%
Answer(s): (a) 70; (b) 56.25%
