The graph shows the number of magazines 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 magazines borrowed by each visitor that Tuesday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 20 + 82 + 24 + 68 + 14
= 208
(b)
Total number of magazines borrowed
= 4 x 20 + 5 x 82 + 6 x 24 + 7 x 68 + 8 x 14
= 80 + 410 + 144 + 476 + 112
= 1222
Average number of magazines borrowed
= 1222 ÷ 208
= 5.875
≈ 6
Answer(s): (a) 208; (b) 6
