The table shows the number of books the children had borrowed. A total of 82 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 + 3 + 5
= 12
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 4 + 2 x 3 + 3 x 5 + 4 x 8
= 57
Number of children who borrowed 5 books each
= (82 - 57) ÷ 5
= 25 ÷ 5
= 5
Answer(s): (a) 12; (b) 5
