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%**.
