Question

At the beginning of the Fall Semester in 2019, Ridgemont High School had a student population of 1,875 students. During the Christmas break, 77 students transferred to other schools and 6 students transferred to Ridgemont High School from other schools. As a result of these changes, by what percent did enrollment at Ridgemont High School decrease? Show your work.

Answer 1

Percentage decrease = 3.79%ercentage decrease = 3.79%

Step-by-step explanation:

Total number of students in 2019 = 1875

During christmas:

There was a decrease of 77 students

This means = 1875 - 77 = 1798 students left in the school

There was also n increase of 6= 1798 + 6

Total number of student remaining = 1804

Percent decrease = (decrease/original amount of student) × 100

Our Decrease will not be 77 because we are told there was an enrolment of 6 students

Decrease = number of students that left - number of new enrolment

Decrease = 77 - 6

Decrease = 71

`\begin{gathered} \text{Percentage decrease = }(71)/(1875)*100 \\ \text{Percentage decrease =0}.0379*100\text{ } \\ \text{Percentage decrease =}3.79\text{ percent} \end{gathered}`
