    I got 65

    Step-by-step explanation:

    The profit will be given as:

    P=$15x-$225

    (where we subtracted the cost of the mower) so that P=$750

    x will be the required number of needed lawns.

    We need to solve:

    $750=$15x-$225

    rearranging:

    x=$750+$225 / $15 = 65 lawns
