Anna and Min have $259. Joelle and Anna have $277. The ratio of Min to Joelle is 3 : 4. How much does Anna have?
Amount that Min has = 3 u
Amount that Joelle has = 4 u
The amount that Anna has is the repeated identity.
Anna + 3 u = 259 --- (1)
Anna + 4 u = 277 --- (2)
(2) - (1)
4 u - 3 u = 277 - 259
1 u = 18
From (1):
Anna + 3 u = 259
Anna + 3 x 18 = 259
Anna + 54 = 259
Amount that Anna has
= 259 - 54
= $205
Answer(s): $205
