Tiffany and Sabrina have $294. Xylia and Tiffany have $314. The ratio of Sabrina to Xylia is 1 : 2. How much does Tiffany have?
Amount that Sabrina has = 1 u
Amount that Xylia has = 2 u
The amount that Tiffany has is the repeated identity.
Tiffany + 1 u = 294 --- (1)
Tiffany + 2 u = 314 --- (2)
(2) - (1)
2 u - 1 u = 314 - 294
1 u = 20
From (1):
Tiffany + 1 u = 294
Tiffany + 1 x 20 = 294
Tiffany + 20 = 294
Amount that Tiffany has
= 294 - 20
= $274
Answer(s): $274
