Research studies have found that the price elasticity of demand for bread is equal to -0.40 and the price elasticity of demand of butter is equal to -1.13. Holding everything else constant, if the price of bread and the price of butter each increase by 10 percent: (a) Will the revenue from sales of bread increase or decrease? (b) Will the revenue from sales of butter increase or decrease?
Use and modify some/all the reactions provided to form the indicated overall reaction according to Hess' Law. • If a reaction is not used in your Hess' Law process, include that indication by multiplying the reaction by "0" • If no modification is needed and the reaction is applied as written below, include that indication by multiplying the reaction by "1" • Use whole numbers and simple fractions (such as "2" or "1/2", not 0.5) and negative signs (such as "-2") where needed Then calculate and report the enthalpy change (in kJ) for the overall reaction in the indicated blank, including units with your written value and rounded to 1 decimal place.
