The line graph shows the number of shirts sold by a shop from January to June in 2014.
- What was the average number of shirts sold per month from January to June in 2014?
- The total number of shirts sold for the same period from January to June in 2013 was 1000. Find the percentage decrease in the total number of shirts sold for the same period from 2013 to 2014
(a)
Total shirts sold from January to June in 2014
= 24 + 74 + 44 + 61 + 31 + 36
= 270
Average shirts sold from January to June in 2014
= 270 ÷ 6
= 45
(b)
Decrease in the number of shirts sold
= 1000 - 270
= 730
Percentage decrease in the total number of shirts sold from 2013 to 2014
=
7301000 x 100%
=
73100x 100%
= 73%
Answer(s): (a) 45; (b) 73%
