Question

Which of the following situations would combine to make zero?

A. Every morning, Max runs three miles around a neighborhood park. He also runs three miles around a nearby lake in the
evening
B. Last week, Margie spent $90 on minor repairs for her car. This week, she spent $90 to refuel the car.
C. When Dan starts preparing the dough for a pizza, he adds two pints of the liquid mix to the flour. He adds two more pints
after kneading the flour for a while.
D. Last month Harmony deposited $250 in her bank account. Two weeks later, she withdrew $250 to make arrangements
for a party

Answer 1

The scenario in which Harmony deposits and then withdraws the same amount from her bank account (D) is the one that would combine to make zero, indicating a net effect of zero in the financial transaction.

Step-by-step explanation:

The student's question relates to interpreting situations that result in a net effect of zero. Let's consider each scenario:

• A. Max's running routine does not involve any sort of addition and subtraction of distances; he simply runs equal amounts at different times of the day.
• B. Margie's spending on car repairs and fuel are two separate expenses. They do not cancel each other out.
• C. Dan's addition of liquid to dough is continual; therefore, there is no subtraction to yield zero.
• D. Harmony's bank balance is affected by depositing and withdrawing the same amount of money. Depositing $250 and later withdrawing the same amount would result in a net transaction of zero, considering no other transactions or interest.

Hence, the correct answer is D. This question falls into the field of Mathematics, specifically in the topic of Algebra and Financial Arithmetic, which often appears in the High School curriculum.
