The graph shows the number of magazines 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 magazines borrowed by each visitor that Saturday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 110 + 96 + 36 + 28 + 130
= 400
(b)
Total number of magazines borrowed
= 4 x 110 + 5 x 96 + 6 x 36 + 7 x 28 + 8 x 130
= 440 + 480 + 216 + 196 + 1040
= 2372
Average number of magazines borrowed
= 2372 ÷ 400
= 5.93
≈ 6
Answer(s): (a) 400; (b) 6
