Final answer:
The provided information about Amelia's motorcycle selling purpose and price is insufficient for a response. However, Freda and Frank's hypothetical scenarios indicate potential profits from selling their assets. Historically, stocks provide higher average returns compared to bonds and savings accounts but with increased risk.
Step-by-step explanation:
To answer this question, we need to bridge various fundamental concepts of economics and business finance. The subject matter pertains to cash transactions on assets, measuring profitability and understanding investment risks. Unfortunately, the information provided does not offer enough context to determine why Amelia wants to sell his motorcycle or the list price. The question details do not relate to the motorcycle but to different economic scenarios, possibly indicating a typo or mix-up.
For the computers being sold at $500, without knowing the cost to make or purchase them, we cannot determine a profit or loss. Similarly, without purchase and selling prices for Amelia's motorcycle, we can't answer that part. However, if we consider Freda's and Frank's house scenarios, we can infer they would both make a profit if they sold their houses at the mentioned prices. Conversely, high-risk investments do not necessarily have low returns; they often offer the potential for higher returns, which is their attractiveness to investors.
When discussing average return over time among stocks, bonds, or savings accounts, historically, stocks have had a higher average return. However, with the greater return comes greater risk. Bonds are generally considered safer than stocks, with moderate returns and low risk compared to stocks, while savings accounts offer the lowest risk and returns. To illustrate economic concepts graphically, a sketch of AC (Average Cost), MC (Marginal Cost), and AVC (Average Variable Cost) curves would typically be applied; however, such a graph requires specific numerical data.
