The line graph shows the number of windbreakers sold by a shop from February to July in 2014.
- What was the average number of windbreakers sold per month from February to July in 2014?
- The total number of windbreakers sold for the same period from February to July in 2013 was 600. Find the percentage decrease in the total number of windbreakers sold for the same period from 2013 to 2014
(a)
Total windbreakers sold from February to July in 2014
= 90 + 58 + 66 + 60 + 25 + 91
= 390
Average windbreakers sold from February to July in 2014
= 390 ÷ 6
= 65
(b)
Decrease in the number of windbreakers sold
= 600 - 390
= 210
Percentage decrease in the total number of windbreakers sold from 2013 to 2014
=
210600 x 100%
=
720x 100%
= 35%
Answer(s): (a) 65; (b) 35%
