Fanny has 10 beads fewer than Vanessa but 40 beads more than Carl. The three children have 180 beads altogether.
- How many beads does Carl have?
- How many beads does Vanessa have?
(a)
Number of beads Vanessa has = 1 u
Number of beads Fanny has = 1 u - 10
Number of beads Carl has = 1 u - 10 - 40 = 1 u - 50
Total number of beads
= 1 u + 1 u - 10 + 1 u - 50
= 3 u - 60
3 u - 60 = 180
3 u = 180 + 60
3 u = 240
1 u = 240 ÷ 3 = 80
Number of beads that Carl has
= 1 u - 50
= 80 - 50
= 30
(b)
Number of beads that Vanessa has
= 1 u
= 80
Answer(s): (a) 30; (b) 80
