Li-Ming owns can ice cream shop. On Saturday, 80 people entered her shop. On Tuesday, 16 people entered her shop. What was the percent decrease in customers from Saturday to Tuesday?

80% decrease

Step-by-step explanation:

A percentage change can be calculated using ...

percent change = ((new value) / (old value) - 1) * 100%

= (16/80 - 1) * 100%

= - 0.80 * 100% = - 80%

The minus sign indicates the change was a decrease.

From Saturday to Tuesday, customers decreased 80%.
