The table shows the toothbrush production rate of One machine. Toothbrush Production Minutes 2 4 6 8 10 Toothbrushes 140 280 | 420 | 560 700 Which of these describes the production rate per minute? 30 toothbrushes 50 toothbrushes 70 toothbrushes d 140 toothbrushes

9514 1404 393

  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

17 1/3

step-by-step explanation:
