Natalie and Jen have $186. Jaslyn and Natalie have $206. The ratio of Jen to Jaslyn is 1 : 2. How much does Natalie have?
Amount that Jen has = 1 u
Amount that Jaslyn has = 2 u
The amount that Natalie has is the repeated identity.
Natalie + 1 u = 186 --- (1)
Natalie + 2 u = 206 --- (2)
(2) - (1)
2 u - 1 u = 206 - 186
1 u = 20
From (1):
Natalie + 1 u = 186
Natalie + 1 x 20 = 186
Natalie + 20 = 186
Amount that Natalie has
= 186 - 20
= $166
Answer(s): $166
