Answer:
The answer is: The buyer made an offer to purchase the home for $70,000
Step-by-step explanation:
When the seller offered to sell his home for $70K, but the buyer only offered $60K, the original offer was discarded, so no legal relationship was established.
When the buyer later offers to buy the home for $70K, a new offer is made creating a legal relationship only if the selling party accepts the offer.
