ANSWER
Ending Balance = $6000
EXPLANATION
We want to use simple interest to find the ending balance.
This means that we have to find the interest and add it to the initial balance.
The formula for simple interest is:
[tex]I=\text{ }\frac{P\cdot\text{ R }\cdot\text{ T}}{100}[/tex]where P = principal = $5000
R = rate = 5%
T = number of years = 4 years
So, the interest on that amount is:
[tex]\begin{gathered} I\text{ = }\frac{5000\cdot\text{ 5 }\cdot\text{ 4}}{100} \\ I\text{ = \$1000} \end{gathered}[/tex]So, the ending balance is the sum of the interest and the principal:
Ending Balance = 5000 + 1000
Ending Balance = $6000
