The graph shows the number of fiction books borrowed by visitors at the local library on a Sunday.
- How many visitors visited the local library that Sunday?
- What was the average number of fiction books borrowed by each visitor that Sunday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 60 + 89 + 35 + 81 + 15
= 280
(b)
Total number of fiction books borrowed
= 1 x 60 + 2 x 89 + 3 x 35 + 4 x 81 + 5 x 15
= 60 + 178 + 105 + 324 + 75
= 742
Average number of fiction books borrowed
= 742 ÷ 280
= 2.65
≈ 3
Answer(s): (a) 280; (b) 3
