X Country has a total of 10 workers. The labour input and quantities output of good A and B are shown in the table below. Labour is mobile factor; capital and land are specific factors of goods A and B respectively. The wage is the only cost of the employers.

Labour Input	Quantity of Output of Good A	MPLA	Quantity of Output of Good B	MPLB
0		---		---
1	84		105
2	129		168
3	171		225
4	210		276
5	237		318
6	261		357
7	282		393
8	297		423
9	309		447
10	315		459

1. Fill in the marginal products of labour for good A (MPL_A) and good B (MPL_B) at labour input of 1 to 10 in the table above. No need to show your calculations for this part. (5 marks)

Suppose the current output of good A is 282 and the price of good A is $20 per unit.

1. What is the output of good B that the country can produce? Explain. (4 marks)

1. Calculate the slope of the production possibility function (with good A on the y-axis and good B on the x-axis) of the current output level. Take 2 decimal places. (5 marks)

1. Calculate the price of good B at the current output level. (5 marks)

1. Calculate the wage per worker in good A at the current output level. (4 marks)

1. Calculate the profit of the capital owner of good A at the current output level. (4 marks)
