Esther and Tina have $249. Kimberly and Esther have $301. The ratio of Tina to Kimberly is 1 : 5. How much does Esther have?
Amount that Tina has = 1 u
Amount that Kimberly has = 5 u
The amount that Esther has is the repeated identity.
Esther + 1 u = 249 --- (1)
Esther + 5 u = 301 --- (2)
(2) - (1)
5 u - 1 u = 301 - 249
4 u = 52
1 u = 52 ÷ 4 = 13
From (1):
Esther + 1 u = 249
Esther + 1 x 13 = 249
Esther + 13 = 249
Amount that Esther has
= 249 - 13
= $236
Answer(s): $236
