Kimberly has some beads in a bag. The number of beads is less than 30. If she gives 4 beads to each pupil, she will have none left. If she gives 8 beads to each pupil, she will need 20 more beads.
- How many pupils does Kimberly have?
- How many beads are there in the bag?
(a)
Total extra number of beads that Kimberly will need = 20
Number of extra beads that Kimberly will give to each pupil
= 8 - 4
= 4
Number of pupils that Kimberly has
= 20 ÷ 4
= 5
(b)
Number of beads that Kimberly has
= 4 x 5
= 20
Answer(s): (a) 5; (b) 20
