I have the answer to 12-23, so I only need the answer to 12-24. Thanks!

Calculate the operating income of Stanmore Corporation in 2012 and 2013. Calculate the growth, price-recovery, and productivity components that explain the change in operating income from 2012 to 2013. Comment on your answer in requirement 2.
