Kimberly and Cindy have $256. Usha and Kimberly have $266. The ratio of Cindy to Usha is 4 : 5. How much does Kimberly have?
Amount that Cindy has = 4 u
Amount that Usha has = 5 u
The amount that Kimberly has is the repeated identity.
Kimberly + 4 u = 256 --- (1)
Kimberly + 5 u = 266 --- (2)
(2) - (1)
5 u - 4 u = 266 - 256
1 u = 10
From (1):
Kimberly + 4 u = 256
Kimberly + 4 x 10 = 256
Kimberly + 40 = 256
Amount that Kimberly has
= 256 - 40
= $216
Answer(s): $216
