The line graph shows the number of blouses sold by a shop from October to March in 2017.
- What was the average number of blouses sold per month from October to March in 2017?
- The total number of blouses sold for the same period from October to March in 2016 was 775. Find the percentage decrease in the total number of blouses sold for the same period from 2016 to 2017
(a)
Total blouses sold from October to March in 2017
= 39 + 24 + 83 + 52 + 84 + 90
= 372
Average blouses sold from October to March in 2017
= 372 ÷ 6
= 62
(b)
Decrease in the number of blouses sold
= 775 - 372
= 403
Percentage decrease in the total number of blouses sold from 2016 to 2017
=
403775 x 100%
=
1325x 100%
= 52%
Answer(s): (a) 62; (b) 52%
