Kylie and Olivia have $217. Linda and Kylie have $229. The ratio of Olivia to Linda is 3 : 4. How much does Kylie have?
Amount that Olivia has = 3 u
Amount that Linda has = 4 u
The amount that Kylie has is the repeated identity.
Kylie + 3 u = 217 --- (1)
Kylie + 4 u = 229 --- (2)
(2) - (1)
4 u - 3 u = 229 - 217
1 u = 12
From (1):
Kylie + 3 u = 217
Kylie + 3 x 12 = 217
Kylie + 36 = 217
Amount that Kylie has
= 217 - 36
= $181
Answer(s): $181
