Explanation:

Step1: Calculate the rate of decrease between Sunday and Monday

The formula for the rate of decrease is $\frac{\text{Initial value}-\text{Final value}}{\text{Initial value}}$.
For Sunday to Monday: Initial value $= 9$, Final value $= 4$.
Rate of decrease $=\frac{9 - 4}{9}=\frac{5}{9}\approx0.556$.

Step2: Calculate the rate of decrease between Wednesday and Thursday

For Wednesday to Thursday: Initial value $= 1$, Final value $= 0$.
Rate of decrease $=\frac{1- 0}{1}=1$.

Answer:

between Wednesday and Thursday
