the number of students at a university increases from 8000 in 1970 to 20,000 in 2000. what was the percent increase in enrollment from 1970 to 2000?
(20,000 - 8,000) / 8,000 = ?
Multiply your answer by 100 to find the percent increase.
150%
To calculate the percentage increase in enrollment from 1970 to 2000, we first need to find the difference between the two enrollment numbers, and then express that difference as a percentage of the initial enrollment in 1970.
Step 1: Find the difference in enrollment
Enrollment in 2000 = 20,000
Enrollment in 1970 = 8,000
Difference = Enrollment in 2000 - Enrollment in 1970
Difference = 20,000 - 8,000
Difference = 12,000
Step 2: Calculate the percentage increase
Percentage increase = (Difference / Enrollment in 1970) * 100
Percentage increase = (12,000 / 8,000) * 100
Percentage increase = 1.5 * 100
Percentage increase = 150%
Therefore, the percentage increase in enrollment from 1970 to 2000 is 150%.
