Answer 1

9514 1404 393

Answer:

c) 70 toothbrushes per minute

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
