Final answer:
The percent decrease from 166 to 37 is 77.71% according to the formula [(change in quantity)/(original quantity)] × 100.
Step-by-step explanation:
To calculate the percent decrease, we use the formula: [(change in quantity)/(original quantity)] × 100.
In this case, the original quantity is 166 and the new quantity is 37. So the change in quantity is 166 - 37 = 129. Thus, the percent decrease is (129/166) × 100 = 77.71%.
