The graph shows the number of magazines borrowed by visitors at the local library on a Thursday.
- How many visitors visited the local library that Thursday?
- What was the average number of magazines borrowed by each visitor that Thursday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 66 + 113 + 117 + 95 + 75
= 466
(b)
Total number of magazines borrowed
= 2 x 66 + 3 x 113 + 4 x 117 + 5 x 95 + 6 x 75
= 132 + 339 + 468 + 475 + 450
= 1864
Average number of magazines borrowed
= 1864 ÷ 466
= 4
≈ 4
Answer(s): (a) 466; (b) 4
