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
= 88 + 60 + 113 + 93 + 16
= 370
(b)
Total number of fiction books borrowed
= 2 x 88 + 3 x 60 + 4 x 113 + 5 x 93 + 6 x 16
= 176 + 180 + 452 + 465 + 96
= 1369
Average number of fiction books borrowed
= 1369 ÷ 370
= 3.7
≈ 4
Answer(s): (a) 370; (b) 4
