can i please get a solution on how to do the parts of question c

Demand, Supply & Trade $[10$ Points$]$

Suppose that domestic market demand and market supply for a good are given by the following equations:

a$)[2$Pts$]$ What is the competitive equilibrium in this market $($without trade$)?$

$a^{**}=80,100-20=4(20)$

b$)[2$Pts$]$ What are Consumer and Producer Surplus at the equilibrium you found in part a$)?$

onsumer and Producer Surplus $at$ the equilibrium you found $in$ part $a$

c$)$ Using the same Demand and Supply $$quations above, now suppose the government opens its $P=40$ borders to trade and the world price of the good is $$10.$ Calculate the following:

$[1$Pt$]$ The price in the domestic market

$[1$Pt$]$ The quantity supplied domestically$*$

$P=\frac{8x}{40}2.$

$Q^s=\frac{?}{Q^d}=$

$Im=$

$[1Pt]$ The quantity demanded domestically$*Q^d=$

$[1Pt]$ The quantity imported $Im=$

Hint: Use the Demand & Supply equations I've given you above

d$)$ Select the correct answers:

$[1$Pt$]$ Does Total Surplus $($CS$+$PS$)$ rise or fall in this case when the government opens its borders to trade?

$[1$Pt$]$ Who benefits more in this case from the decision to open the country's borders to trade?
