The following chart shows "living wage" jobs in Rochester per 1000 working age adults over a 5 year period. Year & 2016 & 2017 & 2018 & 2019 & 2020 Jobs & 675 & 725 & 765 & 795 & 810 What is the average rate of change in the number of living wage jobs from 2016 to 2018? square Jobs/Year What is the average rate of change in the number of living wage jobs from 2018 to 2020? square

## Step 1: Calculate the Average Rate of Change from 2016 to 2018<br />### The average rate of change is calculated by taking the difference in the number of jobs between two years and dividing it by the number of years over which this change occurs. For the period from 2016 to 2018, we have:<br />\[<br />\text{Average Rate of Change} = \frac{\text{Jobs in 2018} - \text{Jobs in 2016}}{\text{2018} - \text{2016}}<br />\]<br />Substituting the values from the table:<br />\[<br />= \frac{765 - 675}{2018 - 2016} = \frac{90}{2} = 45 \text{ Jobs/Year}<br />\]<br /><br />## Step 2: Calculate the Average Rate of Change from 2018 to 2020<br />### Similarly, for the period from 2018 to 2020, the calculation is:<br />\[<br />\text{Average Rate of Change} = \frac{\text{Jobs in 2020} - \text{Jobs in 2018}}{\text{2020} - \text{2018}}<br />\]<br />Substituting the values from the table:<br />\[<br />= \frac{810 - 765}{2020 - 2018} = \frac{45}{2} = 22.5 \text{ Jobs/Year}<br />\]
