Figure out the following based off of Heinz case study. First overview the UV5 Eng pdf to read the case study, then access the UV5 excel file for all the data related to the case study. The Heinz group excel is my attempt to calculate and collect the right stuff to answer the questions below. Please check that and make any necessary corrections to it if possible. Otherwise, answer each of the below questions and make sure to explain any work, excel functions, formula used to get each number and talk about the answer too in a mini paragraph about 3-6 sentences long each that is in relation to the case and proves you have read the case and understand how each factor applies to the whole scenario.
