Question

After COVID-19, Washington State University is focused on increasing its online student population. In 2029, they had 71,946 students. Using Rule of 70, answer the following question: if they increase the number of their admitted students by 6% each year, how long will it take them to double their annual count of online students?

Answer 1

It will take approximately 11.67 years for Washington State University to double its online student population from 71,946 to 143,892 with an annual increase of 6%, according to the Rule of 70.

Step-by-step explanation:

Using the Rule of 70, we can estimate the number of years it will take for Washington State University to double its online student population given a yearly increase of 6%. The Rule of 70 states that to find the doubling time of a quantity growing at a constant annual percentage, you divide 70 by the growth rate. In this case, we divide 70 by the 6% growth rate.

70 ÷ 6% = 70 ÷ 6 = approximately 11.67 years

Therefore, it will take approximately 11.67 years for Washington State University to double its online student population from 71,946 to 143,892 at a 6% annual growth rate.
