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 4170 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 8010 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
= 1150 - 620
= 530
(c)
Only 1640 and 2530 are the only numbers that will give a sum of 4170.
So, the days are Tuesday and Saturday.
(d)
Total newspapers sold from Monday to Saturday
= 1150 + 1640 + 0 + 1670 + 620 + 2530
= 7610
Number of newspapers sold from Monday to Sunday
= 8010
Number of newspapers sold on Sunday
= 8010 - 7610
= 400
Answer(s): (a) Wed; (b) 530; (c) Tue, Sat; (d) 400
