The line graph shows the number of vests sold by a shop from December to May in 2014.
- What was the average number of vests sold per month from December to May in 2014?
- The total number of vests sold for the same period from December to May in 2013 was 900. Find the percentage decrease in the total number of vests sold for the same period from 2013 to 2014
(a)
Total vests sold from December to May in 2014
= 88 + 79 + 57 + 54 + 45 + 73
= 396
Average vests sold from December to May in 2014
= 396 ÷ 6
= 66
(b)
Decrease in the number of vests sold
= 900 - 396
= 504
Percentage decrease in the total number of vests sold from 2013 to 2014
=
504900 x 100%
=
1425x 100%
= 56%
Answer(s): (a) 66; (b) 56%
