Which of the following is a real-world problem that could be solved with the sum of -35.5 + (-16.8)?

Question

*
Hannah bought new headphones for $35.50, and then she decides to returns them.
Jane earned $35.50 babysitting. She then goes to the store and buys a book for $16.80.
A submarine is at 35.5 feet below sea level then travels to 16.8 feet below sea level.
A submarine is at 35.5 feet below sea level and then drops another 16.8 feet.

Answer 1

The sum of -35.5 + (-16.8) represents a scenario where two negative values are added together. This would correspond to a situation where something is getting "deeper" or "more negative."

Out of the provided options, the real-world problem that fits this scenario is:

A submarine is at 35.5 feet below sea level and then drops another 16.8 feet.

In this case, the submarine starts at -35.5 feet and then moves down an additional -16.8 feet, resulting in a total depth of -52.3 feet (which is the sum of -35.5 + (-16.8)).
