Question

Employees with health care benefits
Year Employees
2015 48
2016 43
2017 45
2018 52
2019 50
According to the table, what was the rate of change between 2015 and 2019?
employees per year

Answer 1

To calculate the rate of change in the number of employees with health care benefits between 2015 and 2019, we can use the following formula:

\[ \text{Rate of Change} = \frac{\text{Change in Number of Employees}}{\text{Number of Years}} \]

1. Determine the change in the number of employees:

   • Number of employees in 2015: 48
   • Number of employees in 2019: 50

   \[ \text{Change in Number of Employees} = 50 - 48 = 2 \]

2. Determine the number of years:

   • From 2015 to 2019, the number of years is \(2019 - 2015 = 4\).

3. Calculate the rate of change: \[ \text{Rate of Change} = \frac{2}{4} = 0.5 \]

Thus, the rate of change in the number of employees with health care benefits between 2015 and 2019 is 0.5 employees per year.
