Li-Ming owns an ice cream shop. On Saturday evening from 6:00 PM to 7:00 PM, 80 people entered her shop. On Tuesday from 3:00 PM
to 4:00 PM, 17 people entered her shop. What was the percent decrease in the customers from the given hour on Saturday to the given hour on Tuesday? If necessary, round your answer to the nearest hundredth is a percent.
To find the percent decrease from Saturday to Tuesday, you will find the difference between the number of customers on those days and divided by the total number of customers on Saturday.
By dividing this you will get a decimal, which then can be converted to a percent.
80-17= 63
63/80 = 0.7875 0.7875 = 78.75%
There was a 78.75% decrease from Saturday to Tuesday.
