Can someone break this question down for me to input it into excel

Assume that the City Council in Prescott, Arizona is considering implementing price ceilings on rental units based on the number of bedrooms in the unit. The demand function for rental units (on a single bedroom equivalent basis) is given by Q_D = 120 - 4P and the supply function is given by Q_S = 2P, where P is price and Q is quantity. The Council is considering imposing a ceiling price on rental units of P_max = 16.
