Assume that one day's labor in Argentina can produce either 20 units of cloth or 2 units of wine, while in Chile one day's labor
11111nata11111 [884]

Answer:

cloth production increase is 16  units

wine production increase  is 8 units

Step-by-step explanation:

Given data

Argentina produce cloth = 20 units

Argentina produce wine = 2 units

chile  produce cloth = 24 units

chile  produce  wine = 12 units

to find out

increase in combined output

solution

we know according to question Argentina transfers 2 units of labor from wine to cloth and Chile transfers 1 unit of labor from cloth to wine

therefore cloth production increase = Argentina produced total cloth - before transfer chile  produce cloth ...........1

we can say that Argentina produced total cloth is 2 × 20 = 40  units

so from equation 1

cloth production increase = 40 - 24 = 16  units

cloth production increase is 16  units

and we now can say wine production increase = chile  produce  wine - before transfer  Argentina produce wine  .............2

so Chile produced total wine is 1  × 12 = 12  units

and Argentina produce wine with 2 units of labor  (2 ×  2) =  4

so from equation 2

wine production increase = 12 - 4 = 8 units

wine production increase  is 8 units
