Sabrina has 8 beads fewer than Wendy but 49 beads more than Glen. The three children have 121 beads altogether.
- How many beads does Glen have?
- How many beads does Wendy have?
(a)
Number of beads Wendy has = 1 u
Number of beads Sabrina has = 1 u - 8
Number of beads Glen has = 1 u - 8 - 49 = 1 u - 57
Total number of beads
= 1 u + 1 u - 8 + 1 u - 57
= 3 u - 65
3 u - 65 = 121
3 u = 121 + 65
3 u = 186
1 u = 186 ÷ 3 = 62
Number of beads that Glen has
= 1 u - 57
= 62 - 57
= 5
(b)
Number of beads that Wendy has
= 1 u
= 62
Answer(s): (a) 5; (b) 62
