Question

sofia kept track of the number of games her soccer team won each year.

according to the table, when was the rate of decrease greater?
between 2019 and 2021
between 2017 and 2020

Explanation:

Step1: Calculate rate of decrease between 2019 and 2021

The formula for rate of decrease is \(\frac{\text{Initial value}-\text{Final value}}{\text{Initial value}}\).
Initial value (2019) = 32, Final value (2021) = 24.
Rate of decrease \(=\frac{32 - 24}{32}=\frac{8}{32}=\frac{1}{4}=0.25\)

Step2: Calculate rate of decrease between 2017 and 2020

Initial value (2017) = 22, Final value (2020) = 19.
Rate of decrease \(=\frac{22- 19}{22}=\frac{3}{22}\approx0.136\)

Answer:

Between 2019 and 2021.
