Answer: The ending balance on her statement was $500.
We apply additive property of zero.
Step-by-step explanation:
In other words, [tex]a+0=a[/tex] .

Since she added nothing to her account and nothing means "zero".
therefore, the amount in her account at the time of ending = [tex]500+0=0[/tex] [By additive property of zero ]
