possible to send to the tumorous tissue. The tissue containing a tumor has been divided into six regions: three regions containing tumor and three containing normal tissue. The amount of radiation delivered to each region by a single shot of each of the $5$ types of beams is given in the table below. If each region of normal tissue can handle at most $45$ units of radiation, then how many shots from each beam should be used to maximize the total amount of radiation received by the tumors? Formulate this problem $(10$p$)$ and solve using PuLP in an executable Python $(.$py$)$ file $(25$p$)($Excel solutions will not be accepted!$).$ Data should be loaded directly from the Excel file and the code should use loops as much as possible.
