The graph shows the number of fiction books borrowed by visitors at the local library on a Saturday.
- How many visitors visited the local library that Saturday?
- What was the average number of fiction books borrowed by each visitor that Saturday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 14 + 35 + 105 + 56 + 34
= 244
(b)
Total number of fiction books borrowed
= 3 x 14 + 4 x 35 + 5 x 105 + 6 x 56 + 7 x 34
= 42 + 140 + 525 + 336 + 238
= 1281
Average number of fiction books borrowed
= 1281 ÷ 244
= 5.25
≈ 5
Answer(s): (a) 244; (b) 5
