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 4200 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 8080 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
= 1370 - 900
= 470
(c)
Only 1760 and 2440 are the only numbers that will give a sum of 4200.
So, the days are Tuesday and Thursday.
(d)
Total newspapers sold from Monday to Saturday
= 1370 + 1760 + 900 + 2440 + 0 + 1220
= 7690
Number of newspapers sold from Monday to Sunday
= 8080
Number of newspapers sold on Sunday
= 8080 - 7690
= 390
Answer(s): (a) Fri; (b) 900; (c) Tue, Thu; (d) 390
