The line graph shows the number of vests sold by a shop from August to January in 2017.
- What was the average number of vests sold per month from August to January in 2017?
- The total number of vests sold for the same period from August to January in 2016 was 750. Find the percentage decrease in the total number of vests sold for the same period from 2016 to 2017
(a)
Total vests sold from August to January in 2017
= 49 + 40 + 77 + 54 + 21 + 47
= 288
Average vests sold from August to January in 2017
= 288 ÷ 6
= 48
(b)
Decrease in the number of vests sold
= 750 - 288
= 462
Percentage decrease in the total number of vests sold from 2016 to 2017
=
462750 x 100%
=
77125x 100%
= 61.6%
Answer(s): (a) 48; (b) 61.6%
