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 Tuesday than on Wednesday?
- On which two days were 3470 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 8320 newspapers were sold from Monday to Sunday in the week, how many newspapers were sold on Saturday?
(a)
The store is closed on Thursday because there was no newspapers sold on that day.
(b)
Number of more newspapers sold on Tuesday than on Wednesday
= 1820 - 820
= 1000
(c)
Only 1350 and 2120 are the only numbers that will give a sum of 3470.
So, the days are Monday and Friday.
(d)
Total newspapers sold from Monday to Friday and Sunday
= 1350 + 1820 + 820 + 0 + 2120 + 1480
= 7590
Number of newspapers sold from Monday to Sunday
= 8320
Number of newspapers sold on Saturday
= 8320 - 7590
= 730
Answer(s): (a) Thu; (b) 820; (c) Mon, Fri; (d) 730
