Final answer:
The result is a loss of $100.
Step-by-step explanation:
The result of the team's performance in the Jeopardy game is a loss of $100. Let's break it down:
- A correct answer to a $300 question earns the team $300.
- A wrong answer to a $400 question results in a loss of $400.
- A correct answer to a $500 question earns the team $500.
- A wrong answer to a $400 question results in a loss of $400.
So, the team gained $300 + $500 = $800 but lost $400 + $400 = $800. Therefore, the net result is a loss of $800. Since the team's starting amount was $0, the final result is -$800, which is equivalent to -$100. Therefore, the answer is D. -$100.
