    9.50 + (2.50x) 1.85

    Explanation:

    I think this might be it because you don't really get the time she works for a lawn

    7.65 + 2.50h

    Explanation:

    The original expression for finding her profit is:

    ($9.50x + $2.50h) - 1.85x

    x being the number of lawns she mows

    h being the number of hours she works

    If she were to only mow one lawn, the expression would be:

    ($9.50 (1) + $2.50h) - 1.85 (1)

    h remains constant because we do not know the number of hours she works for

    The above expression simplified:

    ($9.50 + $2.50h) - 1.85

    So, I do ... $9.50 - 1.85 to get ...

    $7.65 + $2.50h
