Johnny has $12 less than Sarah. Sarah has $35 less than Carla. In total, they have $143. How much money does each of them have?

Step-by-step explanation:

Amount with Carla = $ x

Amount with Sarah = x - 35

Amount with Johnny = x - 35 - 12

x + x - 35 + x - 35 - 12 = 143

3x - 82 = 143

3x = 143 + 82

3x = 225

x = 225/3

x = 75

Amount with Carla = $ 75

Amount with Sarah = 75 - 35 = $ 40

Amount with Johnny = 40 - 12 = $ 28
