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
= 46 + 55 + 103 + 31 + 58
= 293
(b)
Total number of fiction books borrowed
= 1 x 46 + 2 x 55 + 3 x 103 + 4 x 31 + 5 x 58
= 46 + 110 + 309 + 124 + 290
= 879
Average number of fiction books borrowed
= 879 ÷ 293
= 3
≈ 3
Answer(s): (a) 293; (b) 3
