What is rachael's opportunity cost for producing 1 belt and 1 neck tie? what is mike's opportunity cost for producing 1 belt and 1 neck tie? who has the comparative advantage in the production of each good? rachel's production belts neckties 0 8 1 12 2 4 3 0 mike's production belts neckties 0 9 3 6 6 3 9 0

So,it will be like each belt Rachel produces keeps her from producing 4 neckties, and each belt Mike produces keeps him from producing 1 necktie.
Rachel can make 12 neckties if she does nothing else and Mike can only 9.
Rachel has the advantage in the necktie department.
Mike can make 9 belts if he does nothing else, and Rachel can only manage 3.
Mike has the advantage in the belt department.

Hope this helps :)
Let me know if you need more help.

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
