The cost of a concert ticket last week was $60.00. This week a concert ticket is $75.00 what is the percent increase of the ticket from last week to this week?

To find the percent increase, you can use the following formula:

Percent Increase = [(New Price - Old Price) / Old Price] x 100

Plugging in the values:

Percent Increase = [($75.00 - $60.00) / $60.00] x 100
Percent Increase = ($15.00 / $60.00) x 100
Percent Increase = 0.25 x 100
Percent Increase = 25%

Therefore, the percent increase of the concert ticket from last week to this week is 25%.
