Calculate and evenly split the bill
Level: Intermediate (score: 3)
Three old friends Bob, Mary, and Alice meet at PyCon and decide to go out to dinner together. They have a wonderful time discussing lambda calculus and laughing about import antigravity.
At the end of the meal, being such good friends they decide to split the check "evenly" 3 ways.
Given an item total add tax (based on the given tax rate) and a tip (applied post-tax) producing a grand total. Next, split the grand total amount as evenly as possible amongst the friends. The sum of the per person split should be equivalent to the grand total.
Tasks
