The table shows the number of books the children had borrowed. A total of 87 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
= 4 + 7 + 1
= 12
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 4 + 2 x 7 + 3 x 1 + 4 x 4
= 37
Number of children who borrowed 5 books each
= (87 - 37) ÷ 5
= 50 ÷ 5
= 10
Answer(s): (a) 12; (b) 10
