Calculate the change in labor and multifactor productivity if Eiskaffee is added to the menu. (Note: Be sure to round each individual labor and multifactor productivity to no fewer than two decimal places before calculating the percentage changes.) The change in labor productivity if Eiskaffee is added to the menu is \%. (Enter your response as a percent rounded to two decimal places and include a minus sian if productivitv decreases. )
