Final answer:
The percent increase in the amount of time Victoria spends getting dressed for school is 400%.
Step-by-step explanation:
To find the percent increase in the amount of time Victoria spends getting dressed for school, we need to calculate the difference in time between elementary school and middle school, and then divide that difference by the original time and multiply by 100.
Elementary school time: 2 minutes
Middle school time: 10 minutes
Difference: 10 - 2 = 8 minutes
Percent increase: (8 / 2) * 100 = 400%
Therefore, the percent increase in the amount of time Victoria spends getting dressed for school is 400%.
