Dana and Jade have $206. Fiona and Dana have $220. The ratio of Jade to Fiona is 4 : 5. How much does Dana have?
Amount that Jade has = 4 u
Amount that Fiona has = 5 u
The amount that Dana has is the repeated identity.
Dana + 4 u = 206 --- (1)
Dana + 5 u = 220 --- (2)
(2) - (1)
5 u - 4 u = 220 - 206
1 u = 14
From (1):
Dana + 4 u = 206
Dana + 4 x 14 = 206
Dana + 56 = 206
Amount that Dana has
= 206 - 56
= $150
Answer(s): $150
