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 + β1 ln(Pepsi Price)+ β2 ln(Cola Price)+ ε have been estimated as follows: 
For the estimated linear model,when the Cola Price is held constant what is the predicted change in the Pepsi Salesif the Pepsi Price increases by 10 cents?
