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 Friday?
- On which two days were 3520 newspapers sold altogether? Give the answer in short form. (Eg Mon, Tue)
- If 9100 newspapers were sold from Monday to Sunday in the week, how many newspapers were sold on Sunday?
(a)
The store is closed on Wednesday because there was no newspapers sold on that day.
(b)
Number of more newspapers sold on Monday than on Friday
= 1410 - 940
= 470
(c)
Only 1840 and 1680 are the only numbers that will give a sum of 3520.
So, the days are Tuesday and Saturday.
(d)
Total newspapers sold from Monday to Saturday
= 1410 + 1840 + 0 + 1630 + 940 + 1680
= 7500
Number of newspapers sold from Monday to Sunday
= 9100
Number of newspapers sold on Sunday
= 9100 - 7500
= 1600
Answer(s): (a) Wed; (b) 470; (c) Tue, Sat; (d) 1600
