Read the conversation and answer the following question.

Customer: OK. My name, the account number, and the date. And then, what next to do?

Mr. Pradipta: The next step you should do is next to the first row, you will see the word "cash". Write down the full amount of cash you are depositing in the blank spaces provided. And there's a box next to the word "cash", put a check in it.

Customer: OK. The amount of money and check the "cash”, right? And then what next?

Mr. Pradipta: Skip down to the last row of blanks. It should say "total," "net" or have a $ sign to its left. Write the total amount of cash in the balnks.

Customer: Yes. Filling out the total. And then what next after that?

Mr. Pradipta: You have to take the deposit slip and cash to the bank teller and hand it over. The teller will deposit your cash and issue you a receipt.

Customer: OK. Then I have to go to the teller. Thank you.

Mr. Pradipta: You are welcome, Sir.
