The graph shows the number of story 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 story books borrowed by each visitor that Saturday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 40 + 26 + 112 + 60 + 62
= 300
(b)
Total number of story books borrowed
= 2 x 40 + 3 x 26 + 4 x 112 + 5 x 60 + 6 x 62
= 80 + 78 + 448 + 300 + 372
= 1278
Average number of story books borrowed
= 1278 ÷ 300
= 4.26
≈ 4
Answer(s): (a) 300; (b) 4
