Am I right?

C is right.

Yes, your answer is correct. In order to determine Lorenzo's new balance, you need to perform the calculations in the correct order.

Lorenzo starts with a balance of $118.00. He then writes a check for $9.00, so you should subtract $9.00 from the balance. Next, he writes another check for $84.25, which means you should subtract $84.25 from the previous result.

After that, Lorenzo deposits $95.00 into his account, so you should add $95.00 to the current balance.

To determine the new balance, the correct series of calculations would be:
118 - 9 - 84.25 + 95 = 119.75

Therefore, pressing the keys in the order listed in option A: 118 - 9 - 84.25 + 95, would give you the correct answer.
