For each interval we get the change in W by taking the ending value less the beginning value. (Round your answers to one decimal place.) 10) Change from 10 to 20=W(20) - W 25.0 25 = 37.8 12.8 12.8 W(30) - W Change from 20 to 30 20 20 43.2-37.8 37.8 5.4 5.4 W(40) - W( Change from 30 to 40 30 W30 43.2 y 43.2 = 46.9 3.7 3.7 W(50) - W40 40) Change from 40 to 50 46.9 = 48.1 46.9 -12 1.2 Step 3 Now we get the average rate of change for each period, (Round your answer to two decimal places.) Change in W Change in workers For 10 to 20 Change in W Change in workers For 20 to 30
