Question

Joseph wants to sell his car. It is a white Toyota Prado, 2008 model. He has looked after it carefully and it has only done 80,000 kilometers. He thinks a fair price to sell it would be 1.2 million vatu.

The next day on 5 March 2022, Joseph puts a notice on the window of his car and on the local supermarket notice board advertising his car for sale. The advertisement states:

"Toyota Prado 2008 model for sale - very good condition, only 80,000 kilometers. Call 7543211 to make a reasonable offer".

6th of march Jennifer rings and says to Joseph "This is a great model car and I'm willing to pay good money for it. I'm happy to pay 1.1 million vatu". Joseph says, "Hmm I'll have to think about it." Jennifer says, "OK well please let me know in writing if you accept my offer." She gives Joseph her postal address and says she will wait to hear from him.

On 10 March, Joseph has still not heard from Jennifer about his letter to her. He decides to give her a call. She is surprised to hear from him and tells him she hasn't received his letter. In the meantime, she has decided not to buy a car after all as she is getting by fine on public transport. She didn't think she needed to tell Joseph this as he was the one who was supposed to contact her.

a) Why is there no binding agreement between Joseph and Jennifer?

and what are the relevant rules?
