Question

tiana is preparing for a dance recital. she practices for 25 minutes on tuesday and 35 minutes on thursday. how did tianas practice time change from tuesday to thursday? tiana increased her practice time by 10 minutes. what is the percent increase in tianas practice time? ? %

Explanation:

Step1: Find the increase in time

The increase in practice time is the difference between Thursday's time and Tuesday's time. So, \( 35 - 25 = 10 \) minutes.

Step2: Calculate the percent increase

The formula for percent increase is \( \text{Percent Increase} = \frac{\text{Increase}}{\text{Original Amount}} \times 100\% \). Here, the original amount (Tuesday's time) is 25 minutes, and the increase is 10 minutes. So, \( \frac{10}{25} \times 100\% = 0.4 \times 100\% = 40\% \).

Answer:

40
