Natalie and Usha have $261. Zoe and Natalie have $273. The ratio of Usha to Zoe is 1 : 2. How much does Natalie have?
Amount that Usha has = 1 u
Amount that Zoe has = 2 u
The amount that Natalie has is the repeated identity.
Natalie + 1 u = 261 --- (1)
Natalie + 2 u = 273 --- (2)
(2) - (1)
2 u - 1 u = 273 - 261
1 u = 12
From (1):
Natalie + 1 u = 261
Natalie + 1 x 12 = 261
Natalie + 12 = 261
Amount that Natalie has
= 261 - 12
= $249
Answer(s): $249
