Why is the calculation of the total cost is wrong. The below is the right numbers but it is different from the solution given and if it comes down to this, will it be 2 or 3 security guards to employ to minimize the loss?
50*25 = 1250
30*25 = 750

4- The manager of Collins Import Autos believes the number of cars sold in a day(Q) depends on two factors: (1) the number of hours the dealership is open (H) and (2) the number of salespersons working that day (S ). After collecting data for two months (53 days), the manager estimates the following log-linear model:
Q = aHbSc
-----
a. Explain how to transform this log-linear model into a linear form that can be estimated using multiple regression analysis.
b. How do you interpret coefficients b and c? If the dealership increases the number of salespersons by 20 percent, what will be the percentage increase in daily sales?
c. Test the overall model for statistical significance at the 5 percent significance level.
