Given: The ATV Company produces a specialty cement used in the construction of roads. ATV is a
price-setting firm and estimates the demand for its cement using a demand function in the linear form:
Q=f( Pc, M, PA)
where Qc = demand for cement/month (in yards) Pc = the price of cement per yard, M= country's tax
revenues per capita, and PR = the price of asphalt per yard. The manager of ATV obtained the following
results in her attempt to estimate the demand for cement in the succeeding months. The results are
presented below:
