Final answer:

The percent decrease in the average waiting time in line is approximately 35.71%.


Step-by-step explanation:

To find the percent decrease in the average amount of time a customer waits in line, we can use the formula:

Percent Decrease = (Initial Value - Final Value) / Initial Value * 100

Substituting the given values:

Percent Decrease = (4.2 - 2.7) / 4.2 * 100 = 35.71%

Therefore, the percent decrease is approximately 35.71%.
