Hi Emma,
Thank you for inviting me to your house last weekend. I had a great time. The chocolate cake your mother made was very delicious. Also, it was fun playing video games with you and your brother.
Next month, there will be a school festival at my school. Would you like to come? It is on November 12th. My class is going to make a haunted house. I hope you can come.
Your friend,
Yumi

💡 Detailed Explanation
本文の第2段落で「Next month, there will be a school festival at my school. Would you like to come?（来月、私の学校で文化祭があります。来ませんか？）」とエマを文化祭に誘っているため、「To invite Emma to her school festival.（エマを文化祭に誘うため）」が正解です。
