Okay I need to know which readability formula fit each one of these Scenarios. Scenario 1: The trip scheduled for Mexico during spring break has been cancelled due to the bankruptcy of the bus company. You must tell 25 of your classmates that the trip has been cancelled and that they have lost their $100 deposit. How will you convey the infomation and still uphold their goodwill toward you? Scenario 2: Your local bank made a mistake on your printed checks. Additionally the bank charged you for the checks, even though this order was supposed to be complimentary for customers opening a new account. How would you draft a letter that allows your irritation to work for, rather than against you?

Question

It's helpful if you put the school subject in the subject line -- you'll get quicker answers if teachers know what they're heading into.

Also, please don't post a question more than once. That wastes time, too.

You can find more if you go to www.google.com and enter readability levels.
