The line graph shows the number of newspapers sold at a store over a week.
- On which day was the store closed? Give the answer in short form. (Eg Mon)
- How many more newspapers were sold on Monday than on Friday?
- On which two days were 4230 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 9200 newspapers were sold from Monday to Sunday in the week, how many newspapers were sold on Sunday?
(a)
The store is closed on Wednesday because there was no newspapers sold on that day.
(b)
Number of more newspapers sold on Monday than on Friday
= 1690 - 800
= 890
(c)
Only 1770 and 2460 are the only numbers that will give a sum of 4230.
So, the days are Tuesday and Saturday.
(d)
Total newspapers sold from Monday to Saturday
= 1690 + 1770 + 0 + 1520 + 800 + 2460
= 8240
Number of newspapers sold from Monday to Sunday
= 9200
Number of newspapers sold on Sunday
= 9200 - 8240
= 960
Answer(s): (a) Wed; (b) 890; (c) Tue, Sat; (d) 960
