The line graph shows the number of jumpsuits sold by a shop from March to August in 2013.
- What was the average number of jumpsuits sold per month from March to August in 2013?
- The total number of jumpsuits sold for the same period from March to August in 2012 was 1000. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2012 to 2013
(a)
Total jumpsuits sold from March to August in 2013
= 94 + 96 + 47 + 54 + 90 + 75
= 456
Average jumpsuits sold from March to August in 2013
= 456 ÷ 6
= 76
(b)
Decrease in the number of jumpsuits sold
= 1000 - 456
= 544
Percentage decrease in the total number of jumpsuits sold from 2012 to 2013
=
5441000 x 100%
=
68125x 100%
= 54.4%
Answer(s): (a) 76; (b) 54.4%
