The line graph shows the number of vests sold by a shop from June to November in 2016.
- What was the average number of vests sold per month from June to November in 2016?
- The total number of vests sold for the same period from June to November in 2015 was 1000. Find the percentage decrease in the total number of vests sold for the same period from 2015 to 2016
(a)
Total vests sold from June to November in 2016
= 27 + 87 + 85 + 47 + 60 + 96
= 402
Average vests sold from June to November in 2016
= 402 ÷ 6
= 67
(b)
Decrease in the number of vests sold
= 1000 - 402
= 598
Percentage decrease in the total number of vests sold from 2015 to 2016
=
5981000 x 100%
=
299500x 100%
= 59.8%
Answer(s): (a) 67; (b) 59.8%
