The ability to produce a good or service at a lower opportunity cost than another.

Explanation:

"Comparative advantage" is an economic term first introduced by economist David Ricardo in 1817. And to understand this term, first one must have solid  grasp on what opportunity cost means. The opportunity cost is defined as the potential benefit that you lose when choosing one option over another; to make it more simple, here is an example: When you finish high school, you have two options whether to go to college to study or you start working. If you decide to study, the opportunity cost is the money you would recieve as payment for your work. Either way, a decision has to be made and both options have benefits that you would lose if you choose the other.

Now, having cleared this, you can identify a comparative advantage when a  person, company or country is able to produce goods or services more efficiently than others and, rather than producing everything, they can focus on what gives them higher margins. This way opportunity costs are minimized and earnings are increased.

step-by-step explanation:

this is really simple i saw that there was only one term (5x) and thought if that was 15 what would i have to multiply everything else to get it there? well if 5x became 15 then x would have to be 3 so plug the 3 in the x for the other equations and you get 15 for the other ones. so there you go. : )
