If the number of students taking online courses is increasing at a rate of 7% per year, How long will it take for the number of students taking online courses to double?

===============================================

Work Shown:

The formula to use is , where,

A = final amount after t years

P = starting amount

r = growth rate

t = number of years

----------

The starting amount does not matter. Let's just make it some nice round number such as P = 100. This will double to A = 2*P = 2*100 = 200.

The growth rate in this case is r = 0.07

We want to solve for t

and

 D) 10.24 years

Step-by-step explanation:

Since the rate increases at the same rate every year, it is an exponential function.  Use the formula:   where

Given: A = 2P, P = P, r = 7% (0.07), t = unknown

It will take about 10.24 years for the number of students taking online courses to double.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
