Solve it clearly

QUESTION 8 A foreign mining firm is considering investing in a project near Archer River in Queensland. A recent CBA shows that the project has a net benefit of $180,000 in the market CBA and $140,000 in the efficiency CBA. It is estimated that the local community will suffer environmental damage measured at $30,000 while the downstream residents (non-referent group) will suffer a lower water quality measured at $10,000. If the firm will get a net benefit of $120,000 after-tax, calculate the net benefit for the referent group CBA. Round your answer to the nearest dollar and do not put the $ sign.QUESTION 7 Suppose a project will require 2500 local labour hours at the construction stage. Assume it can hire 40 % of labour who would otherwise be unemployed and 60% of labour will be sourced from elsewhere in the economy. The market wage of labour is $45 per hour while the leisure time for unemployed labour is measured at $20 per hour. Match the following values you would use in the CBA: Total labour cost (market price) A. 25000 Total labour cost (efficiency price) B. 87500 Total net employment C. 62500 Total opportunity cost of labour D. 20000 E. 112500
