3. Adele and Bella are sisters. On 1st February Adele meets her sister for a drink and tells her

she is looking for a new sports car. Bella replies that she wants to sell her red Ferrari as there

is now a better model available and that she is happy to sell it to her sister 'on a business

basis'. Bella says she wants 'about 100,000' for it. That evening Adele sends an email to Bella

saying, 'I accept your offer to sell the car for 100,000 and will transfer the money in a few

days.' On 3rd February Bella sends Adele an email that says: 'Don't be stupid I wouldn't sell

the car for that, I want 125,000 for it. To avoid any further misunderstanding, do not email Bella

again unless you do not want the car at this price.' Adele was so annoyed on reading the first

sentence of Bella's email that she deleted it without reading further and did not reply. Three

weeks later Bella rang Adele and demanded 125,000, offering to deliver the car. Advise

Adele.
