Answer:
Amount with Salma = $ 23
The amount with Chris = $69
Amount with Jim = $ 32
Explanation:
Let the amount with Salma = $ x
The amount with Chris = 3*x = 3x
Amount with Jim = x + 9
Total in their wallets = $124
x + 3x + x +9 = 124 {combine like terms}
5x+ 9 = 124 {Subtract 9 from both sides}
5x = 124 - 9
5x = 115 {Divide both sides by 5}
x = 115/5
x = 23
Amount with Salma = $ 23
The amount with Chris = 3*23 = $69
Amount with Jim = 23 + 9 = $ 32
