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?

Question

A. 8%

B. 15%

C. 20%

D. 25%

Answer 1

To calculate the percent increase in the cost of the concert ticket, you can use the following formula:

\[ \text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]

In this case, the old value (last week's ticket price) is $60.00, and the new value (this week's ticket price) is $75.00.

1. Calculate the difference between the new value and the old value:

\[ 75.00 - 60.00 = 15.00 \]

2. Now, divide the difference by the old value:

\[ \frac{15.00}{60.00} = 0.25 \]

3. Finally, multiply by 100 to get the percent increase:

\[ 0.25 \times 100 = 25% \]

Therefore, the percent increase in the ticket price from last week to this week is 25%.

The correct answer is D. 25%.
