Question

an administrator at the department of motor vehicles (dmv) tracked the average wait time from month to month. according to the table, when was the rate of decrease greater? between march and may between june and july

Explanation:

Step1: Calculate rate of decrease between March and May

The formula for rate of decrease is $\frac{\text{Initial value}-\text{Final value}}{\text{Initial value}}$.
For March ($56$) and May ($53$), the rate of decrease is $\frac{56 - 53}{56}=\frac{3}{56}\approx0.0536$.

Step2: Calculate rate of decrease between June and July

For June ($56$) and July ($55$), the rate of decrease is $\frac{56 - 55}{56}=\frac{1}{56}\approx0.0179$.

Answer:

between March and May
