The line graph shows the number of dresses sold by a shop from January to June in 2014.
- What was the average number of dresses sold per month from January to June in 2014?
- The total number of dresses sold for the same period from January to June in 2013 was 768. Find the percentage decrease in the total number of dresses sold for the same period from 2013 to 2014
(a)
Total dresses sold from January to June in 2014
= 61 + 63 + 69 + 40 + 86 + 65
= 384
Average dresses sold from January to June in 2014
= 384 ÷ 6
= 64
(b)
Decrease in the number of dresses sold
= 768 - 384
= 384
Percentage decrease in the total number of dresses sold from 2013 to 2014
=
384768 x 100%
=
12x 100%
= 50%
Answer(s): (a) 64; (b) 50%
