The line graph shows the number of jumpsuits sold by a shop from March to August in 2015.
- What was the average number of jumpsuits sold per month from March to August in 2015?
- The total number of jumpsuits sold for the same period from March to August in 2014 was 750. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2014 to 2015
(a)
Total jumpsuits sold from March to August in 2015
= 26 + 20 + 91 + 51 + 69 + 37
= 294
Average jumpsuits sold from March to August in 2015
= 294 ÷ 6
= 49
(b)
Decrease in the number of jumpsuits sold
= 750 - 294
= 456
Percentage decrease in the total number of jumpsuits sold from 2014 to 2015
=
456750 x 100%
=
76125x 100%
= 60.8%
Answer(s): (a) 49; (b) 60.8%
