The correct answer is:  [A]:  " -10 + c = 10 " .

Explanation:

 
The beginning balance is:  " -$10 ". 

The "ending balance", or "current balance", is:  "$10" .

So, the beginning balance is a "negative value", or a "deficit".

To get the change, "c" , 

either:  " 10 − c = -10 " ; 

or:  " -10 + c = 10 " .


Among the answer choices given, the correct answer choice provided is:


Answer choice:  [A]:   " -10 + c = 10 " .
