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
= 130 + 83 + 37 + 119 + 112
= 481
(b)
Total number of magazines borrowed
= 5 x 130 + 6 x 83 + 7 x 37 + 8 x 119 + 9 x 112
= 650 + 498 + 259 + 952 + 1008
= 3367
Average number of magazines borrowed
= 3367 ÷ 481
= 7
≈ 7
Answer(s): (a) 481; (b) 7
