The graph shows the number of magazines borrowed by visitors at the local library on a Monday.
- How many visitors visited the local library that Monday?
- What was the average number of magazines borrowed by each visitor that Monday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 76 + 30 + 65 + 46 + 11
= 228
(b)
Total number of magazines borrowed
= 4 x 76 + 5 x 30 + 6 x 65 + 7 x 46 + 8 x 11
= 304 + 150 + 390 + 322 + 88
= 1254
Average number of magazines borrowed
= 1254 ÷ 228
= 5.5
≈ 6
Answer(s): (a) 228; (b) 6
