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 calculate the percent increase, we can use the formula:
Percent increase = [(New price - Old price) / Old price] * 100
Substitute the values into the formula:
Percent increase = [($75.00 - $60.00) / $60.00] * 100
Percent increase = [($15.00) / $60.00] * 100
Percent increase = 0.25 * 100
Percent increase = 25%
Therefore, the ticket price has increased by 25% from last week to this week.
