    30 new workers were brought in to join the crew

    Step-by-step explanation:

    1 situation

    15*12=x (x is the full work)

    2 situation

    3*15+3*y=x

    15*12=3*15+3*y

    180=45+3*y

    3y=180-45

    3y=135

    y = 135/3=45

    y include the 15 person road crew that works from the beginning.

    So, the new workers are 30. (45-30)
