It is believed that the sales volume of one-liter Pepsi bottles depends on the price of the bottle and the price of a one-liter bottle of Coca-Cola.The following data have been collected for a certain sales region. 
Using Excel's regression,the linear model Pepsi Sales = β0 + β1Pepsi Price + β2Cola Price + ε and the log-log model ln(Pepsi Sales)= β0 + β1ln(Pepsi Price)+ β2ln(Cola Price)+ ε have been estimated as follows: 
Using the estimated linear model,calculate the predicted Pepsi Sales when the Pepsi Price is $1.50 and the Cola Price is $1.25.
