The line graph shows the number of blouses sold by a shop from November to April in 2014.
- What was the average number of blouses sold per month from November to April in 2014?
- The total number of blouses sold for the same period from November to April in 2013 was 752. Find the percentage decrease in the total number of blouses sold for the same period from 2013 to 2014
(a)
Total blouses sold from November to April in 2014
= 94 + 29 + 32 + 74 + 20 + 33
= 282
Average blouses sold from November to April in 2014
= 282 ÷ 6
= 47
(b)
Decrease in the number of blouses sold
= 752 - 282
= 470
Percentage decrease in the total number of blouses sold from 2013 to 2014
=
470752 x 100%
=
58x 100%
= 62.5%
Answer(s): (a) 47; (b) 62.5%
