Tammy and Tina have $314. Gem and Tammy have $327. The ratio of Tina to Gem is 3 : 4. How much does Tammy have?
Amount that Tina has = 3 u
Amount that Gem has = 4 u
The amount that Tammy has is the repeated identity.
Tammy + 3 u = 314 --- (1)
Tammy + 4 u = 327 --- (2)
(2) - (1)
4 u - 3 u = 327 - 314
1 u = 13
From (1):
Tammy + 3 u = 314
Tammy + 3 x 13 = 314
Tammy + 39 = 314
Amount that Tammy has
= 314 - 39
= $275
Answer(s): $275
