Linda and Anna have $318. Emma and Linda have $332. The ratio of Anna to Emma is 3 : 4. How much does Linda have?
Amount that Anna has = 3 u
Amount that Emma has = 4 u
The amount that Linda has is the repeated identity.
Linda + 3 u = 318 --- (1)
Linda + 4 u = 332 --- (2)
(2) - (1)
4 u - 3 u = 332 - 318
1 u = 14
From (1):
Linda + 3 u = 318
Linda + 3 x 14 = 318
Linda + 42 = 318
Amount that Linda has
= 318 - 42
= $276
Answer(s): $276
