The line graph shows the number of jumpsuits sold by a shop from April to September in 2012.
- What was the average number of jumpsuits sold per month from April to September in 2012?
- The total number of jumpsuits sold for the same period from April to September in 2011 was 804. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2011 to 2012
(a)
Total jumpsuits sold from April to September in 2012
= 22 + 80 + 99 + 90 + 59 + 52
= 402
Average jumpsuits sold from April to September in 2012
= 402 ÷ 6
= 67
(b)
Decrease in the number of jumpsuits sold
= 804 - 402
= 402
Percentage decrease in the total number of jumpsuits sold from 2011 to 2012
=
402804 x 100%
=
12x 100%
= 50%
Answer(s): (a) 67; (b) 50%
