The line graph shows the number of shirts sold by a shop from June to November in 2017.
- What was the average number of shirts sold per month from June to November in 2017?
- The total number of shirts sold for the same period from June to November in 2016 was 720. Find the percentage decrease in the total number of shirts sold for the same period from 2016 to 2017
(a)
Total shirts sold from June to November in 2017
= 32 + 45 + 44 + 86 + 62 + 55
= 324
Average shirts sold from June to November in 2017
= 324 ÷ 6
= 54
(b)
Decrease in the number of shirts sold
= 720 - 324
= 396
Percentage decrease in the total number of shirts sold from 2016 to 2017
=
396720 x 100%
=
1120x 100%
= 55%
Answer(s): (a) 54; (b) 55%
