    Answer:

      c)  70 toothbrushes per minute

    Step-by-step explanation:

    The table tells you that production is 140 toothbrushes in 2 minutes. Dividing toothbrushes by minutes gives you the “per minute” value:

      (140 toothbrushes)/(2 minutes) = (140/2) toothbrushes/minute

      = 70 toothbrushes/minute
