Kylie and Victoria have $288. Raeann and Kylie have $342. The ratio of Victoria to Raeann is 1 : 4. How much does Kylie have?
Amount that Victoria has = 1 u
Amount that Raeann has = 4 u
The amount that Kylie has is the repeated identity.
Kylie + 1 u = 288 --- (1)
Kylie + 4 u = 342 --- (2)
(2) - (1)
4 u - 1 u = 342 - 288
3 u = 54
1 u = 54 ÷ 3 = 18
From (1):
Kylie + 1 u = 288
Kylie + 1 x 18 = 288
Kylie + 18 = 288
Amount that Kylie has
= 288 - 18
= $270
Answer(s): $270
