Answer:
You should invest in US bonds because you will be able to earn a higher return than if you build and sell microwaves.
Explanation:
alternative 1, build and sell microwave ovens:
initial outlay = $500,000
net cash flow per year = $225,000 - $200,000 = $25,000
alternative 2, invest in US securities:
investment = $500,000
net cash flow per year = $500,000 x 10% = $50,000
Opportunity costs are the benefits lost or extra costs resulting from choosing one activity or investment over another.
If you choose to build and sell microwaves, you will not be able to invest in bonds, and therefore, your net income will decrease by $25,000 - $50,000 = -$25,000.
Instead, if you invest in bonds and not microwaves, your net income will increase by $50,000 - $25,000 = $25,000.
