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 4190 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 8540 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
= 1350 - 660
= 690
(c)
Only 1920 and 2270 are the only numbers that will give a sum of 4190.
So, the days are Monday and Friday.
(d)
Total newspapers sold from Monday to Friday and Sunday
= 1920 + 1350 + 660 + 0 + 2270 + 1610
= 7810
Number of newspapers sold from Monday to Sunday
= 8540
Number of newspapers sold on Saturday
= 8540 - 7810
= 730
Answer(s): (a) Thu; (b) 660; (c) Mon, Fri; (d) 730
