The line graph shows the number of dresses sold by a shop from August to January in 2013.
- What was the average number of dresses sold per month from August to January in 2013?
- The total number of dresses sold for the same period from August to January in 2012 was 950. Find the percentage decrease in the total number of dresses sold for the same period from 2012 to 2013
(a)
Total dresses sold from August to January in 2013
= 79 + 43 + 78 + 20 + 91 + 31
= 342
Average dresses sold from August to January in 2013
= 342 ÷ 6
= 57
(b)
Decrease in the number of dresses sold
= 950 - 342
= 608
Percentage decrease in the total number of dresses sold from 2012 to 2013
=
608950 x 100%
=
1625x 100%
= 64%
Answer(s): (a) 57; (b) 64%
