On Monday Amir lost $15 to Kenneth playing integer poker. He
was tight he lost, so he kept playing. On Tuesday Amir lost
another $4. On Wednesday he did not win or lose so he did not go
home crying like a little, little baby. But, on Thursday he lost
another $7. By then he owed Kenneth $8. So being smart, he
decided to stop playing. How much money did Amir have before
he started playing?
