Suppose that the quantity supplied S and quantity demanded D of T-shirts at a concert are given by the following functions where p is the price.

S (p) = -200+40p

D (p) = 1150-50 p.

a. Find the equilibrium price for the T-shirts at this concert. The equilibrium price is

b. Determine the prices for which quantity demanded is greater than quantity supplied.

c. What will eventually happen to the price of the T-shirts if the quantity demanded is greater than the quantity supplied?

    Step-by-step explanation:

    The demand function is expressed as

    D (p) = 1150-50p

    The supply function is expressed as S (p) = -200 + 40p

    Where

    p represents the price

    A) The equilibrium price is the price at which the quantity supplied and the quantity demanded would be equal. Therefore

    1150 - 50p = - 200 + 40p

    40p + 50p = 1150 + 200

    90p = 1350

    p = 1350/90

    p = 15

    The equilibrium price is $15

    b) For quantity demanded to be greater than quantity supplied, the price would be

    1150 - 50p > - 200 + 40p

    40p + 50p > 1150 + 200

    90p > 1350

    p > 1350/90

    p > 15

    The price would be greater than 15

    c) if the quantity demanded is greater than the quantity supplied, the prices of the T shirt would increase.
