    Hello Jim,

    let c be the wage for one craftsman
    let a be the wage for one apprentice

    Then you'll get 2 equations:
    16c + 5a = 740
    9c + 30a = 740

    Multiply the 1rst equation by 6 and subtract the 2nd equation. You'll get:

    87c = 3700. Thus c = 42.53 and a = 11.91

    The results are rounded to 2 decimals.
