Question

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?..

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.

Now, plug in the values:

\[
\text{Percent Increase} = \left( \frac{75.00 - 60.00}{60.00} \right) \times 100
\]

Calculating the increase:

\[
75.00 - 60.00 = 15.00
\]

Then, divide by the old value:

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

Now, multiply by 100 to get the percent:

\[
0.25 \times 100 = 25
\]

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