Answer
# Explanation:
## Step1: Identify the formula for percent - decrease
Percent decrease=$\frac{\text{Original amount}-\text{New amount}}{\text{Original amount}}\times100\%$
## Step2: Determine the original and new amounts
The original amount (fall enrollment) is 40 students, and the new amount (spring enrollment) is 28 students.
## Step3: Calculate the difference
$40 - 28=12$
## Step4: Calculate the percent - decrease
Percent decrease=$\frac{40 - 28}{40}\times100\%=\frac{12}{40}\times100\% = 0.3\times100\%=30\%$
