We are given
initial population is 5891
so, [tex]P_i=5891[/tex]
Population after 50 years is 5178
so, [tex]P_f=5178[/tex]
now, we can find percent error
so, we can use formula
[tex]error=\frac{P_i-P_f}{P_i}\times 100[/tex]
now, we can plug values
[tex]error=\frac{5891-5178}{5891}\times 100[/tex]
now, we can simplify it
so, we get
The percent decrease is 12.1032%.........Answer
First: work out the difference (decrease) between the two numbers you are comparing by the formula
Decrease = Original Number - New Number
In your case,
[tex]\text{Decrease}=5891-5178=713.[/tex]
Second: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
In your case,
[tex]\%\text{Decrease}=\dfrac{713}{5891}\cdot 100\%=12.1\%.[/tex]
Answer: The percent decrease is approximately 12.1%.
