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
= 26 + 101 + 57 + 25 + 51
= 260
(b)
Total number of magazines borrowed
= 5 x 26 + 6 x 101 + 7 x 57 + 8 x 25 + 9 x 51
= 130 + 606 + 399 + 200 + 459
= 1794
Average number of magazines borrowed
= 1794 ÷ 260
= 6.9
≈ 7
Answer(s): (a) 260; (b) 7
