Ivory and Gillian have $226. Hazel and Ivory have $236. The ratio of Gillian to Hazel is 4 : 5. How much does Ivory have?
Amount that Gillian has = 4 u
Amount that Hazel has = 5 u
The amount that Ivory has is the repeated identity.
Ivory + 4 u = 226 --- (1)
Ivory + 5 u = 236 --- (2)
(2) - (1)
5 u - 4 u = 236 - 226
1 u = 10
From (1):
Ivory + 4 u = 226
Ivory + 4 x 10 = 226
Ivory + 40 = 226
Amount that Ivory has
= 226 - 40
= $186
Answer(s): $186
