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 4550 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 9670 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
= 1830 - 770
= 1060
(c)
Only 2010 and 2540 are the only numbers that will give a sum of 4550.
So, the days are Tuesday and Saturday.
(d)
Total newspapers sold from Monday to Saturday
= 1830 + 2010 + 0 + 1650 + 770 + 2540
= 8800
Number of newspapers sold from Monday to Sunday
= 9670
Number of newspapers sold on Sunday
= 9670 - 8800
= 870
Answer(s): (a) Wed; (b) 1060; (c) Tue, Sat; (d) 870
