- What was the average number of magazines borrowed by each visitor that Saturday? Give your answer to the nearest whole number.
(a)
Total number of visitors
= 44 + 51 + 29 + 59 + 67
= 250
(b)
Total number of magazines borrowed
= 3 x 44 + 4 x 51 + 5 x 29 + 6 x 59 + 7 x 67
= 132 + 204 + 145 + 354 + 469
= 1304
Average number of magazines borrowed
= 1304 ÷ 250
= 5.216
≈ 5
