Answer all questions. In your calculations and in your final answer, use at least $4$ numbers to the right of the decimal point. Even though these problems and answers are about "percentages", for your answers do NOT type in the percent sign, BUT INSTEAD USE DECIMAL FORMAT $($i$.$e$.5\%$ should be typed in as $\mathrm{.}05)$

You are examining an investment opportunity. It would require you to pay money today and then receive payments semi$-$annually from that investment. Since the payments you expect to receive are semi$-$annual, you would like to know your semi$-$annual version of your own required return. You require $10\%$ per year. What semi$-$annual rate $($i$.$e$.$ periodic return per six months$)$ do you require $($i$.$e$.$ need to earn such that this implies $10\%$ earned per year when you get to compound semi$-$annually$)?$
