2. (16%) Build-Right Concrete Products produces specialty cement used in construction of highways. BuildRight is a price setting firm and estimates the demand for its cement by the State Highway Department using a demand function in the nonlinear form: Q = aP\"MCP Where Q = yards of cement demanded monthly, P = the price of BuildRight's cement per yard, M = state tax revenues per capita, and PD = the price of asphalt per yard. The manager at Build-Right transforms the nonlinear relation into a linear relation for estimation. The estimation results are presented below: DEPENDENT VARIABLE: LNQ R-SQUARE F-RATIO P-VALUE 0N F OBSERVATIONS: 34 0.678 14.323 0.02311 PARAMETER STANDARD VARIABLE ESTIMATE ERROR T-RATIO P-VALUE INTERCEPT 4 1.50 2.67 0.0122 LNP 0.8 0.25 3.20 0.0032 LNM 0.1816 4.13 0.0003 LNPR . 0.200 3.00 0.0054 Given the above, calculate the estimated percentage change in the quantity of cement demanded a- if the price of Build-Right's cement per yard (P) increases by 3% (Show your calculations) b- if the price of asphalt per yard (PR) increases by 2% (Show your calculations)
