HI. I need assistance with the following question.

Assume that:

Demand : Q(d)= 100-20P

Supply : Q(s)= -20+20P

The government then decides to impose subsidy to consumers to assist them to purchase solar PV panels

Calculate impact of SUBSIDY on CONSUMERS

I already calculated coordinates of each axes and equilibrium price and quantity which can be found in the attachment.

I'm looking forward to your help :)
