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
= 30 + 134 + 25 + 49 + 107
= 345
(b)
Total number of fiction books borrowed
= 2 x 30 + 3 x 134 + 4 x 25 + 5 x 49 + 6 x 107
= 60 + 402 + 100 + 245 + 642
= 1449
Average number of fiction books borrowed
= 1449 ÷ 345
= 4.2
≈ 4
Answer(s): (a) 345; (b) 4
