The graph shows the number of fiction books borrowed by visitors at the local library on a Monday.
- How many visitors visited the local library that Monday?
- What was the average number of fiction books borrowed by each visitor that Monday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 60 + 45 + 121 + 76 + 94
= 396
(b)
Total number of fiction books borrowed
= 4 x 60 + 5 x 45 + 6 x 121 + 7 x 76 + 8 x 94
= 240 + 225 + 726 + 532 + 752
= 2475
Average number of fiction books borrowed
= 2475 ÷ 396
= 6.25
≈ 6
Answer(s): (a) 396; (b) 6
