The line graph shows the number of jumpsuits sold by a shop from August to January in 2015.
- What was the average number of jumpsuits sold per month from August to January in 2015?
- The total number of jumpsuits sold for the same period from August to January in 2014 was 792. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2014 to 2015
(a)
Total jumpsuits sold from August to January in 2015
= 78 + 67 + 80 + 32 + 50 + 89
= 396
Average jumpsuits sold from August to January in 2015
= 396 ÷ 6
= 66
(b)
Decrease in the number of jumpsuits sold
= 792 - 396
= 396
Percentage decrease in the total number of jumpsuits sold from 2014 to 2015
=
396792 x 100%
=
12x 100%
= 50%
Answer(s): (a) 66; (b) 50%
