Kimberly and Jean have $241. Raeann and Kimberly have $286. The ratio of Jean to Raeann is 1 : 4. How much does Kimberly have?
Amount that Jean has = 1 u
Amount that Raeann has = 4 u
The amount that Kimberly has is the repeated identity.
Kimberly + 1 u = 241 --- (1)
Kimberly + 4 u = 286 --- (2)
(2) - (1)
4 u - 1 u = 286 - 241
3 u = 45
1 u = 45 ÷ 3 = 15
From (1):
Kimberly + 1 u = 241
Kimberly + 1 x 15 = 241
Kimberly + 15 = 241
Amount that Kimberly has
= 241 - 15
= $226
Answer(s): $226
