Answer:To represent the possible return rates for the two investment options, we can use compound inequalities.
For the first option, the return is expected to be more than 8% but less than 12%. This can be represented as:
8% < return on first option < 12%
For the second option, the return should be at least 6%. This can be represented as:
return on second option ≥ 6%
Combining both inequalities, we can represent the possible return rates for the two investment options as:
8% < return on first option < 12% AND return on second option ≥ 6%
