Ella saved = 1488 $ if Ella and Lily's savings is $1908. Ella and Anna's savings $2244 and ratio of Lily to Anna's savings is 5 : 9
Step-by-step explanation:
Let say Ella saved = E $
The sum of Ella and Lily's savings is $1908
=> Lily saves = 1908 - E $
Ella and Anna's savings sum up to $2244
=> Anna Saved = 2244 - E $
The ratio of Lily to Anna's savings is 5 : 9.
1908 - E : 2244 - E :: 5 : 9
=> 9 * (1908 - E) = 5 (2244 - E)
=> 17172 - 9E = 11220 - 5E
=> 4E = 5952
=> E = 1488
Ella saved = 1488 $
