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 3370 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 9820 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
= 1340 - 670
= 670
(c)
Only 1400 and 1970 are the only numbers that will give a sum of 3370.
So, the days are Tuesday and Thursday.
(d)
Total newspapers sold from Monday to Saturday
= 1340 + 1400 + 670 + 1970 + 0 + 1430
= 6810
Number of newspapers sold from Monday to Sunday
= 9820
Number of newspapers sold on Sunday
= 9820 - 6810
= 3010
Answer(s): (a) Fri; (b) 670; (c) Tue, Thu; (d) 3010
