Here's how you could fill in the invitation, assuming some details from Exercise 4 (which isn't provided, so I'm making them up!). You'll need to adjust it based on the actual information from your exercise.
PARTY! PARTY! PARTY!
My party is on Saturday, July 15th!
It starts at 2:00 PM and ends at 6:00 PM.
It's at my house: 123 Main Street.
We'll have games, music, and lots of fun!
There will be pizza and cake!
Please RSVP by July 10th so I know how much food to get.
Can't wait to see you there!
