Answer:  $5.22  (in the year 2021)
========================================================
Explanation:
The year 2021 is 22 years after 1999 since
2021 - 1999 = 22
That means we'll plug x = 22 into the equation given to us
P = 144*(0.86)^x
P = 144*(0.86)^22
P = 5.21588994768589 which is approximate
P = 5.22 rounding to the nearest cent
The share price is about $5.22 in the year 2021.
This assumes that the 14% decline keeps happening year after year; however, in reality, stocks are more complicated and fluctuate more randomly if anything. 
 
        
             
        
        
        
Answer:
5/6
Step-by-step explanation:
You write the question as such: 5/9 divided by 2/3. 
After that, you keep the first fraction, flip the sign and the fraction. 
You will get: 5/9 multiplied by 3/2. 
When you get this, you then cross multiply and simplify as such. 
5/3 multiplied by 1/2. 
5/6 would be your solution.
