Hydra Capital offers a range of 1-year investment products for customers. The details for two such investment products are as follows:

Investment A is a security tied to market performance. For an initial investment of $100, the security, one year from today, will be worth:

• $140 if the market is good,
• $105 if the market is moderate, and
• $80 if the market is bad.

Investment B is a security also tied to the performance of the market. However, it performs better the worse the market is doing. For an initial investment of $100, the second security, one year from today, will be worth:

• $70 if the market is good
• $90 if the market is moderate, and
• $170 if the market is bad.
