The table shows the number of books the children had borrowed. A total of 78 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
= 3 + 6 + 6
= 15
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 3 + 2 x 6 + 3 x 6 + 4 x 5
= 53
Number of children who borrowed 5 books each
= (78 - 53) ÷ 5
= 25 ÷ 5
= 5
Answer(s): (a) 15; (b) 5
