The table shows the number of books the children had borrowed. A total of 71 books were borrowed by the children.
- How many children borrowed 2 books or less?
- How many children borrowed 5 books?
(a)
Number of children who borrowed 2 books or less
= 8 + 7
= 15
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 8 + 2 x 7 + 3 x 5 + 4 x 1
= 41
Number of children who borrowed 5 books each
= (71 - 41) ÷ 5
= 30 ÷ 5
= 6
Answer(s): (a) 15; (b) 6
