Yen has 14 erasers fewer than Risa but 45 erasers more than Wesley. The three children have 212 erasers altogether.
- How many erasers does Wesley have?
- How many erasers does Risa have?
(a)
Number of erasers Risa has = 1 u
Number of erasers Yen has = 1 u - 14
Number of erasers Wesley has = 1 u - 14 - 45 = 1 u - 59
Total number of erasers
= 1 u + 1 u - 14 + 1 u - 59
= 3 u - 73
3 u - 73 = 212
3 u = 212 + 73
3 u = 285
1 u = 285 ÷ 3 = 95
Number of erasers that Wesley has
= 1 u - 59
= 95 - 59
= 36
(b)
Number of erasers that Risa has
= 1 u
= 95
Answer(s): (a) 36; (b) 95
