After day 3 you have $ 0.08

After day 4 you have $ 0.16

After day 5 you have $ 0.32

After day 6 you have $ 0.64

After day 7 you have $ 1.28

After day 8 you have $ 2.56

After day 9 you have $ 5.12

After day 10 you have $ 10.24

After day 11 you have $ 20.48

After day 12 you have $ 40.96

After day 13 you have $ 81.92

After day 14 you have $ 163.84

After day 29 you have $ 5,368,709.12

After day 30 you have $10,737,418.24

My code is System.out.printf("After day %d you have $%,13.2f\n", day, money);

Answer

Try this:

```
System.out.printf("After day %2d you have $%,13.2f\n", day, money);
```

%2d will right indent the number, and will take 2 charater space.
