Last week, 420 people went to the skating rink. this week, only 294 people went. what is the percent decrease for the skating rink attendance? %

Number of people that went to the skating rink last week = 420
Number of people that went to the skating rink this week = 294
Then
Decrease in the number
of people going to the skating rink this week = 420 - 294
                                                                       = 126
Percentage decrease in the number
of people going to the skating rink this week = (126/420) * 100
                                                                       = 1260/42
                                                                       = 30 percent
So there is 30% decrease in the percentage of people going to the skating rink this week.
