Question

You are given a pair of equations, one representing a supply curve and the other representing a demand curve, where p is the unit price for x items.
5 p + x - 972 = 0
and
21 p - x - 32 = 0

a. Identify which is the supply curve and demand curve and the appropriate domain. Put the domains in interval notation .
Domain of the supply curve:
Domain of the demand curve:
b. Determine the market equilibrium. Equilibrium: x = ? p = ?
c. Determine the revenue function. Revenue function R(x)= ?
d. Determine the revenue at market equalibrum:
