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
= 78 + 48 + 117 + 27 + 30
= 300
(b)
Total number of fiction books borrowed
= 1 x 78 + 2 x 48 + 3 x 117 + 4 x 27 + 5 x 30
= 78 + 96 + 351 + 108 + 150
= 783
Average number of fiction books borrowed
= 783 ÷ 300
= 2.61
≈ 3
Answer(s): (a) 300; (b) 3
