Gem has 8 erasers fewer than Joelle but 34 erasers more than Flynn. The three children have 199 erasers altogether.
- How many erasers does Flynn have?
- How many erasers does Joelle have?
(a)
Number of erasers Joelle has = 1 u
Number of erasers Gem has = 1 u - 8
Number of erasers Flynn has = 1 u - 8 - 34 = 1 u - 42
Total number of erasers
= 1 u + 1 u - 8 + 1 u - 42
= 3 u - 50
3 u - 50 = 199
3 u = 199 + 50
3 u = 249
1 u = 249 ÷ 3 = 83
Number of erasers that Flynn has
= 1 u - 42
= 83 - 42
= 41
(b)
Number of erasers that Joelle has
= 1 u
= 83
Answer(s): (a) 41; (b) 83
