Suppose we have a 2-person world, with only stephen and his friend lebron. suppose that stephen can move 48 boxes or bake 24 cookies in an hour. suppose that lebron could move 36 boxes or bake 9 cookies in an hour. is trade possible? choose one:
a. no, trade isn't possible, because lebron has an absolute advantage in both making cookies and moving boxes.
b. yes, trade is possible. stephen should make cookies while lebron moves boxes, because stephen has a comparative advantage in making cookies and lebron has a comparative advantage in moving boxes.
c. no, trade isn't possible, because stephen has an absolute advantage in both making cookies and moving boxes.

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)
