Looking for a little help with the following economics price restrictions problem.
Qd=50-P
Qs=(1/2)P-10
I already have computed equilibrium price and quantity.
Q=10
P=40
a.) $48 Price Floor. Find Quantity Demanded, Quantity Supplied, Compute full economic price received by sellers.
b.) $39 Price Ceiling. Find Quantity Demanded, Quantity Supplied, Compute full economic price received by sellers.

Thank you in advance!
