Question
A farm produced 1,626 kg wool in year 2,015 and 1,589 kg wool in year 2,019. What was the rate of change of the wool production?
Solution
To calculate the rate of change, you need to subtract the final value from the initial value, then divide by the number of years that have passed.
Here are the steps:
-
Subtract the wool production in 2019 from the wool production in 2015: 1589 kg - 1626 kg = -37 kg. This means the wool production decreased by 37 kg over these four years.
-
Next, calculate the number of years between 2015 and 2019: 2019 - 2015 = 4 years.
-
Finally, divide the change in production by the number of years to find the rate of change: -37 kg / 4 years = -9.25 kg/year.
So, the rate of change of the wool production from 2015 to 2019 was -9.25 kg per year. The negative sign indicates that the production decreased.
