Create a scenario that involves a change modeled by a positive number, but an end result modeled by a negative number.

Question

Example: Irene is scuba diving 20 feet below sea level. Her sister tells her to swim 5 feet up towards the surtace to see a school of fish.
NOTE: To receive credit for this question, you must come up with a unique scenario that involves a positive change and results in a negative number. The example provided is to get you thinking about what is appropriate.

Answer 1

Adrian is working as a diver in a research program studying coral reefs. He starts his day by diving to a depth of 30 feet below sea level to observe the marine life. While he is conducting his research, he discovers an interesting specimen and decides to descend deeper to examine it further. He swims an additional 10 feet downwards to a depth of 40 feet below sea level.

Despite the fascinating find, he realizes he has gone too deep and needs to return to a safe depth. When he swims back up 8 feet, he calculates his new depth. Starting from 40 feet below sea level, swimming up 8 feet results in:

\[ -40 + 8 = -32 \]

So, after swimming up 8 feet, Adrian is now at a depth of 32 feet below sea level, which is still a negative number.

Answer 2

Please make this as short as the example

Answer 3

Lila is a submarine pilot exploring the ocean, starting her dive at a depth of 25 feet below sea level. She descends an additional 15 feet to examine a shipwreck. After spending time there, she decides to ascend 10 feet.

Now, she is at:

\(-25 - 15 + 10 = -30\)

So, Lila is now at a depth of 30 feet below sea level.
