First, work out the difference(increase) between the two numbers you are comparing. So, the difference would be <em>100-80</em>, which will equal <em>20</em>.
Then, divide the increase by the original number and multiply the answer by 100. So, that would be <em>20÷100</em>, which would be <em>0.2</em>, then it would be <em>0.2⋅100</em>, so back to <em>20</em>.
The percent of increase should be 20.

12

<h3>What is exponential function?</h3>
An exponential function is a mathematical function of the following form: f ( x ) = a^x. where x is a variable, and a is a constant called the base of the function.
Given:
A= 210 million
P= A e^(kt)
225 = 210 * e ^ (0.0069t)
225/210= e ^ (0.0069t)
1.07 = e ^ (0.0069t)
Taking log on both side
log 1.047 = 0.0069 t log e
t= log ( 1.047) / 0.0069
t= 6.65
Hence, value of t is 6.65.
