The line graph shows the number of blouses sold by a shop from February to July in 2014.
- What was the average number of blouses sold per month from February to July in 2014?
- The total number of blouses sold for the same period from February to July in 2013 was 930. Find the percentage decrease in the total number of blouses sold for the same period from 2013 to 2014
(a)
Total blouses sold from February to July in 2014
= 75 + 47 + 40 + 37 + 96 + 77
= 372
Average blouses sold from February to July in 2014
= 372 ÷ 6
= 62
(b)
Decrease in the number of blouses sold
= 930 - 372
= 558
Percentage decrease in the total number of blouses sold from 2013 to 2014
=
558930 x 100%
=
35x 100%
= 60%
Answer(s): (a) 62; (b) 60%
