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? A. 8% B. 15% C. 20% D. 25%

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

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

In this case, the old price is $60.00 and the new price is $75.00.

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 ticket from last week to this week is 25%.

The correct answer is D. 25%
