Lucy has 7 beads fewer than Olivia but 32 beads more than Cole. The three children have 230 beads altogether.
- How many beads does Cole have?
- How many beads does Olivia have?
(a)
Number of beads Olivia has = 1 u
Number of beads Lucy has = 1 u - 7
Number of beads Cole has = 1 u - 7 - 32 = 1 u - 39
Total number of beads
= 1 u + 1 u - 7 + 1 u - 39
= 3 u - 46
3 u - 46 = 230
3 u = 230 + 46
3 u = 276
1 u = 276 ÷ 3 = 92
Number of beads that Cole has
= 1 u - 39
= 92 - 39
= 53
(b)
Number of beads that Olivia has
= 1 u
= 92
Answer(s): (a) 53; (b) 92
