Question

Lorenzo has a checkbook balance of $118.00. He writes two checks, one for $9.00 and one for $84.25. He then deposits $95.00. Finally, he uses his calculator to determine his new balance. Which one of the following series represents the correct order in which he should press the keys on his calculator?

Answer 1

The answer is 118 - 9 - 84.25 + 95.

Answer 2

The correct answer is 118 - 9 - 84.25 + 95. He starts out with 118 as his checkbook balance, and since he's writing two checks, that means he's subtracting money from his account. Then, when he deposits money, that means he's adding to his account, which indicates addition.
