Answer:
Explanation:
1) Order the numbers using the data from 2001-2004
70,60,81,19
2) Add them all together
70+60+81+19= 230
3) Divide the answer you got by the amount of numbers there are
70,60,81,19=4 numbers
230/4 = 57.5
4) Therefore the average rate of change between 2001-2004 is 58 employees (since you can't have a fraction of a person you would have to round)
Hope this helps!
