In a hypothetical market for bottled water, the market demand and supply are described by the following equations:- Market Demand: QD = 1150 - 100P- Market Supply: QS = -100 + 400Pa) Find the equilibrium price and quantity.To find the equilibrium, set the quantity demanded (QD) equal to the quantity supplied (QS):\[1150 - 100P = -100 + 400P\]Solve for the equilibrium price (P) and substitute it back into either the demand or supply equation to find the equilibrium quantity.

Equilibrium is the state of having balanced economic forces. Given that, Qd= 1150-100P and Qs=-100+400PEquilibrium Qd=Qs1150-100P=-100+400P1250=500PPrice (P)= 2.5Quantity (Q)= 1150-100P1150-100*2.5= 900 Thus, Equilibrium Price= 2.5 and Equilibrium Quantity= 900

Question

In a hypothetical market for bottled water, the market demand and supply are described by the following equations:

- Market Demand: QD = 1150 - 100P
- Market Supply: QS = -100 + 400P

a) Find the equilibrium price and quantity.

To find the equilibrium, set the quantity demanded (QD) equal to the quantity supplied (QS):

\[1150 - 100P = -100 + 400P\]

Solve for the equilibrium price (P) and substitute it back into either the demand or supply equation to find the equilibrium quantity.
