At any given time, an economy is able to make only two goods. One of these is good X and the other is either A, B, C or D. The table gives the output levels of goods A, B, C and D for each level of good X when the economy’s resources are fully employed. Which good has to be produced together with good X to show a production possibility curve with increasing costs?
- AGood A: X 0,100,200,300,400 with A 0,20,40,60,80
- BGood B: X 0,100,200,300,400 with B 110,70,40,20,0
- CGood C: X 0,100,200,300,400 with C 120,90,60,30,0
- DGood D: X 0,100,200,300,400 with D 140,120,90,50,0
