    Set up a system of equations.

    that means:

    2a+3k=47

    3a+5k=74.75

    Which means

    6a+9k=141

    6a+10k=149.5

    If we subtract we get that

    -1k=-8.5

    One kid costs 8.5

    Plug this back into the equation and you get that 25.5+2a=47. That means adults cost 10.75

    Kids: 8.5

    Adults: 10.75
