Fanny and Julie have $141. Nora and Fanny have $174. The ratio of Julie to Nora is 1 : 4. How much does Fanny have?
Amount that Julie has = 1 u
Amount that Nora has = 4 u
The amount that Fanny has is the repeated identity.
Fanny + 1 u = 141 --- (1)
Fanny + 4 u = 174 --- (2)
(2) - (1)
4 u - 1 u = 174 - 141
3 u = 33
1 u = 33 ÷ 3 = 11
From (1):
Fanny + 1 u = 141
Fanny + 1 x 11 = 141
Fanny + 11 = 141
Amount that Fanny has
= 141 - 11
= $130
Answer(s): $130
