Your boss at Best Bison is kind of cheap. You have complete your business correspondence on an Apple 2e computer from 1983. The 2e is the only apple that turns green. (That's a fact.) It's made out of apple parts, and the keys stick. You are in charge of the billing department, and you keep producing invoices with extra 0's in them. Compose two correction letters in which you include all the requisite parts of a business letter. One should apologize for the clerical error, and the other should apologize for giving the customer a coronary. Then compose a memo to your boss, Suzy Q. Bison in which you request a computer update and demonstrate your knowledge of the requirements of a memo.
