Based on the audience and purpose of each scenario, determine whether the tone of the presentation should be formal or informal.

miguel is writing to the principal to ask for a
change in the policy involving the use of vending
machines during the school day.
brody is writing a letter to his boss to
her for the birthday present.
jessica is writing a note to her little sister to remind her
to pick up her toys before their parents get home.
rihanna is writing a letter to her friend to
tell her what she did over summer break.

If Miguel is writing to the principal to persuade him why vending machines should be used during the school day, it should be formal. This is because the principal has an important position and is more likely to consider your opinion if you write to him/her formally.
Brody should also write formally because his boss is an important figure and especially with work, you definitely want to be professional.
Jessica can write informally because her sister isn’t a professional person she needs to address in that way. Jessica is just writing a reminder, not a letter.
And finally, Rihanna can be informal because she’s writing to a friend. Her friend most likely doesn’t care about how professional the letter sounds; she just wants to know what Rihanna did over summer break.
Hope this helps! \(^•^)/
