Mr. bailey purchased some groceries that cost d dollars. he paid $50 bill. write an expression for the amount of he will receives

- "r"; represents the amount he will receive

- "d"; represents the cost

- Mr. Bailey paid a 50$ bill

So the amount Mr. Bailey paid subtracted by the cost of the groceries will equal the amount he will recieve in change. That should look something like this; " 50 - d = r"
