See a solution process below:

The decrease can be found by subtracting last months deliveries from this months deliveries:

#42 - 50 = -8#

John made #8# less deliveries in June than in May.

==============================

If you are looking for the percent decrease we can use this formula for calculating the percent change in a value between two points in time:

#p = (N - O)/O *100#

Where:

#p# is the percent change - what we are solving for in this problem.

#N# is the New Value - 42 deliveries in this problem.

#O# is the Old Value - 50 deliveries in this problem.

Substituting and solving for #p# gives:

#p = (42 - 50)/50 *100#

#p = -8/50 *100#

#p = -800/50#

#p = -16#

Between May and June there was a 16% decrease in the number of deliveries John made.
