The line graph shows the number of jumpsuits sold by a shop from February to July in 2016.
- What was the average number of jumpsuits sold per month from February to July in 2016?
- The total number of jumpsuits sold for the same period from February to July in 2015 was 650. Find the percentage decrease in the total number of jumpsuits sold for the same period from 2015 to 2016
(a)
Total jumpsuits sold from February to July in 2016
= 60 + 32 + 76 + 39 + 80 + 25
= 312
Average jumpsuits sold from February to July in 2016
= 312 ÷ 6
= 52
(b)
Decrease in the number of jumpsuits sold
= 650 - 312
= 338
Percentage decrease in the total number of jumpsuits sold from 2015 to 2016
=
338650 x 100%
=
1325x 100%
= 52%
Answer(s): (a) 52; (b) 52%
