The line graph shows the number of blazers sold by a shop from February to July in 2016.
- What was the average number of blazers sold per month from February to July in 2016?
- The total number of blazers sold for the same period from February to July in 2015 was 600. Find the percentage decrease in the total number of blazers sold for the same period from 2015 to 2016
(a)
Total blazers sold from February to July in 2016
= 43 + 25 + 93 + 100 + 54 + 63
= 378
Average blazers sold from February to July in 2016
= 378 ÷ 6
= 63
(b)
Decrease in the number of blazers sold
= 600 - 378
= 222
Percentage decrease in the total number of blazers sold from 2015 to 2016
=
222600 x 100%
=
37100x 100%
= 37%
Answer(s): (a) 63; (b) 37%
