Reem has $28.53 remaining after paying her friend back.
The correct interpretation of the sum in the context of the problem is:
$16.80 is the amount Zuri has left from their earnings last week after purchasing the video game.
To arrive at this interpretation, you start with the given information that Zuri earned $56.80 and spent $40 on a video game. To find out how much Zuri has left, you subtract the amount spent from the earnings:
$56.80 - $40 = $16.80
Therefore, $16.80 is the amount Zuri has left from their earnings after purchasing the video game.
