Okay

mathematics hates me. :disappointed:

UGHHH

WAIT, IT'S 30 I'M-

He lost $100. The robber steals the $100 and uses it to by $70 worth of food, and his total change is $30.

The thief has received $70 worth of groceries , and $30 in change. Which in total is a $100 profit lost for the owner.

Okay so the man takes $100 From the then gives the $100 back to the owner when he pays for the goods but then the owner has then lost $70 worth of goods but then The owner also loses $30 when he gives the man his change so then $70 worth of goods He bought + $30 change = $100 I think??? Okay Honestly I’m failing math but I can do this???? I don’t even think I’m correct
