The line graph shows the number of blazers sold by a shop from September to February in 2017.
- What was the average number of blazers sold per month from September to February in 2017?
- The total number of blazers sold for the same period from September to February in 2016 was 744. Find the percentage decrease in the total number of blazers sold for the same period from 2016 to 2017
(a)
Total blazers sold from September to February in 2017
= 77 + 70 + 44 + 37 + 82 + 62
= 372
Average blazers sold from September to February in 2017
= 372 ÷ 6
= 62
(b)
Decrease in the number of blazers sold
= 744 - 372
= 372
Percentage decrease in the total number of blazers sold from 2016 to 2017
=
372744 x 100%
=
12x 100%
= 50%
Answer(s): (a) 62; (b) 50%
