Anna and Marion have $167. Jean and Anna have $184. The ratio of Marion to Jean is 3 : 4. How much does Anna have?
Amount that Marion has = 3 u
Amount that Jean has = 4 u
The amount that Anna has is the repeated identity.
Anna + 3 u = 167 --- (1)
Anna + 4 u = 184 --- (2)
(2) - (1)
4 u - 3 u = 184 - 167
1 u = 17
From (1):
Anna + 3 u = 167
Anna + 3 x 17 = 167
Anna + 51 = 167
Amount that Anna has
= 167 - 51
= $116
Answer(s): $116
