The table shows the number of books the children had borrowed. A total of 75 books were borrowed by the children.
- How many children borrowed 3 books or less?
- How many children borrowed 5 books?
(a)
Number of children who borrowed 3 books or less
= 9 + 3 + 8
= 20
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 9 + 2 x 3 + 3 x 8 + 4 x 4
= 55
Number of children who borrowed 5 books each
= (75 - 55) ÷ 5
= 20 ÷ 5
= 4
Answer(s): (a) 20; (b) 4
