I'm struggling to calculate these practice questions could you help?

Suppose the government is considering reducing carbon monoxide emissions in an industrial area that is in close proximity to a residential area. Two firms are responsible for the emissions. The firms have the following total control (TC) and marginal control costs (MC) of reducing emissions:

Firm (1):MC1=2Q1

TC1= (Q1)2

Firm (2):MC2=3Q2

TC2= 1.5(Q2)2

WhereMC1andMC2are the marginal control costs andQ1andQ2are the quantity of emissions reduced of firm (1) and firm (2) respectively. With no controls, each firms has emissions of 30 units each.

1. Suppose the government sets a uniform abatement standard of 20 units for each firm.Calculate the total cost to each firm.
2. Calculate the cost-effective allocation of reducing emissions if a total reduction of 40 units is required. What is the total cost for each firm and how does this compare to part 1?
3. What is the aggregate (both firms) cost of reducing emissions in parts 1 and 2?
4. What policy options are available to the government that achieve cost effective reductions in emissions? Explain
