80... (20 was their.... 💪)

$100 he just replaced the $70 with groceries

$100

$30 plus the cost of the $70 of goods, which presumably would be less than $70. That's all they lost. The$100 is in the register. It's the same as if the man stole $30 from the register and stole the goods he walked out with. That's what the store lost.

100

$170 The 30 in change is part of the original 100 so you wouldn't count it twice

30 idk how yall niggas getting 100,150,200

200

For those not getting it, he paid using that same $100 bill, so It is back where it started. As explained by another user, the store lost $30 plus the real value of the items he took.

They lost 170
