Answer
$5600(1+rt)$
Work Step by Step
The original expression is $A=5600+5600rt$.
Because $5600$ is a standalone number and also the coefficient to $rt$ in the original equation, we can easily factor it out.
$5600(1+rt)$
To check your work use the distributive property.
If you multiply $5600$ by $1$, you have $5600$.
$1\times5600=5600$
If you multiply $5600$ by $rt$, you have $5600rt$.
$5600\times rt =5600rt$
$5600+5600rt=5600(1+rt)$
