Answer to Question 1

B

Answer to Question 2

It is profitable to hire this worker because the worker's value of marginal product is 150 a day (the price, 10, times the marginal product, 15 units), which exceeds the wage rate of 100 a day. The worker creates 150 more revenue for the firm at a cost of only 100. Hence it is profitable to hire this worker.
