Question
Consider a perfectly competitive market for frozen meals. The demand for frozen meals is given by Pd=100-Q and the supply of frozen meals is given by Ps=10+2Q. Which of the answers below is true? Group of answer choices
If P=80, then there is excess demand
If P=80, there is no excess supply and no excess demand
If P=80, the market is at its equilibrium state
If P=80, then there is excess supply
None of the other answers are correct
Solution
To determine whether there is excess demand or supply, we need to compare the quantity demanded and the quantity supplied at the given price.
-
Calculate the quantity demanded (Qd) at P=80 using the demand equation:
Qd = 100 - P Qd = 100 - 80 Qd = 20
-
Calculate the quantity supplied (Qs) at P=80 using the supply equation:
Qs = (P - 10) / 2 Qs = (80 - 10) / 2 Qs = 35
-
Compare Qd and Qs:
Since Qs (35) is greater than Qd (20), there is excess supply in the market.
So, the correct answer is: If P=80, then there is excess supply.
