according to the graph, when was the rate of decrease greater?
between may and july
between march and june

Explanation:

Step1: Calculate rate between May and July

May: $95, July: $55. Time: 2 months.
Rate = $\frac{95 - 55}{2} = \frac{40}{2} = 20$ per month.

Step2: Calculate rate between March and June

March: $90, June: $75. Time: 3 months.
Rate = $\frac{90 - 75}{3} = \frac{15}{3} = 5$ per month.

Step3: Compare rates

20 > 5, so rate of decrease is greater between May and July.

Answer:

between May and July
