The graph shows the number of novels borrowed by visitors at the local library on a Tuesday.
- How many visitors visited the local library that Tuesday?
- What was the average number of novels borrowed by each visitor that Tuesday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 14 + 54 + 80 + 12 + 40
= 200
(b)
Total number of novels borrowed
= 3 x 14 + 4 x 54 + 5 x 80 + 6 x 12 + 7 x 40
= 42 + 216 + 400 + 72 + 280
= 1010
Average number of novels borrowed
= 1010 ÷ 200
= 5.05
≈ 5
Answer(s): (a) 200; (b) 5
