AE = $5 + 0.0025L,
where AE represents the average expenditure ($/unit) and L represents units of labor hired per unit of time. The demand for labor is based on the following expression:
MP = 5 - 0.001L,
where MP represents marginal product of labor. Revenue from the final good is $5 per unit sold in a competitive market.
