can you help me IRAC this contracts assignment?

Facts:Debbie owned and operated a party supply company called "Partyline".

Debbie had recently expanded her inventory of tables and chairs that she offered for rent.

I will need to rent tables and chairs for that day for 100 people, said Pete.

Debbie replied, "I just need to double-check to make sure we will have enough tables and chairs available, but I am quite sure we can provide you with tables and chairs for 100 guests."

"No problem," Said Pete, "you can let me know sometime within the next two weeks."

Between June 3 and 6 Debbie received a large number of bookings to rent tables and chairs.

On June 7 Debbie took out a second advertisement stating, "Partyline is no longer able to honor its June rental special. Please contact us for your July party needs."

On June 12 Pete called Debbie and told her that he was counting on the table and chair rentals for his garden party.

Debbie apologized but said she would be unable to provide Pete with the table and chair rentals.

Thank you
