The graph shows the number of fiction books borrowed by visitors at the local library on a Wednesday.
- How many visitors visited the local library that Wednesday?
- What was the average number of fiction books borrowed by each visitor that Wednesday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 96 + 139 + 132 + 94 + 27
= 488
(b)
Total number of fiction books borrowed
= 1 x 96 + 2 x 139 + 3 x 132 + 4 x 94 + 5 x 27
= 96 + 278 + 396 + 376 + 135
= 1281
Average number of fiction books borrowed
= 1281 ÷ 488
= 2.625
≈ 3
Answer(s): (a) 488; (b) 3
