W_NU = 30 - 0.04L W_U = 30 - 0.10L.
The wage rate is W in $/hr. and the number of workers per day is L.
a. Determine the total demand for plumbers.
b. Calculate the total market wage rate of plumbers assuming that unionized and nonunionized plumbers get the same wage rate.
c. If the unionized workers succeeded in getting their wage increased to $20.00 per hour, how many unionized workers would lose their jobs?
