Tammy and Fanny have $314. Olivia and Tammy have $326. The ratio of Fanny to Olivia is 4 : 5. How much does Tammy have?
Amount that Fanny has = 4 u
Amount that Olivia has = 5 u
The amount that Tammy has is the repeated identity.
Tammy + 4 u = 314 --- (1)
Tammy + 5 u = 326 --- (2)
(2) - (1)
5 u - 4 u = 326 - 314
1 u = 12
From (1):
Tammy + 4 u = 314
Tammy + 4 x 12 = 314
Tammy + 48 = 314
Amount that Tammy has
= 314 - 48
= $266
Answer(s): $266
