Emily and Julie have $330. Kimberly and Emily have $352. The ratio of Julie to Kimberly is 3 : 5. How much does Emily have?
Amount that Julie has = 3 u
Amount that Kimberly has = 5 u
The amount that Emily has is the repeated identity.
Emily + 3 u = 330 --- (1)
Emily + 5 u = 352 --- (2)
(2) - (1)
5 u - 3 u = 352 - 330
2 u = 22
1 u = 22 ÷ 2 = 11
From (1):
Emily + 3 u = 330
Emily + 3 x 11 = 330
Emily + 33 = 330
Amount that Emily has
= 330 - 33
= $297
Answer(s): $297
