Ghella [55]

Answer:

C. $0.30/bu

Explanation:

Given that

Cash cost = $1.50/bu

Opportunity cost of labour = $0.30/bu

Opportunity cost of Land = $0.40/bu

Sales from corn = $2.50/bu

Recall that economic profits = Total income - Total expenses - opportunities cost

Therefore

Economic profits = 2.50 - 1.50 - (0.30 + 0.40)

= 2.50 - 1.50 - 0.70

= 0.30

Therefore, economic profits = $0.30/bu
