The graph shows the number of magazines borrowed by visitors at the local library on a Sunday.
- How many visitors visited the local library that Sunday?
- What was the average number of magazines borrowed by each visitor that Sunday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 102 + 114 + 16 + 53 + 49
= 334
(b)
Total number of magazines borrowed
= 3 x 102 + 4 x 114 + 5 x 16 + 6 x 53 + 7 x 49
= 306 + 456 + 80 + 318 + 343
= 1503
Average number of magazines borrowed
= 1503 ÷ 334
= 4.5
≈ 5
Answer(s): (a) 334; (b) 5
