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 Wednesday?
- On which two days were 3610 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 7540 newspapers were sold from Monday to Sunday in the week, how many newspapers were sold on Sunday?
(a)
The store is closed on Friday because there was no newspapers sold on that day.
(b)
Number of more newspapers sold on Monday than on Wednesday
= 1270 - 610
= 660
(c)
Only 1340 and 2270 are the only numbers that will give a sum of 3610.
So, the days are Tuesday and Thursday.
(d)
Total newspapers sold from Monday to Saturday
= 1270 + 1340 + 610 + 2270 + 0 + 1900
= 7390
Number of newspapers sold from Monday to Sunday
= 7540
Number of newspapers sold on Sunday
= 7540 - 7390
= 150
Answer(s): (a) Fri; (b) 610; (c) Tue, Thu; (d) 150
