Final answer:
Yash's response to Yasmine with additional terms was a counteroffer, which was not accepted, meaning the original offer was not validly accepted. Yash may only be entitled to restitution, not the offered salary or the additional relocation money.
Step-by-step explanation:
The question pertains to contract law, specifically the exchange of offer and acceptance in forming a legally binding agreement. When Yasmine made the offer and Yash responded with a condition about relocation money, he effectively made a counteroffer. Since Yasmine did not expressly agree to the counteroffer and it appears that the original position was filled, Yash's acceptance did not result in a completed contract under the initial terms. Therefore, he would not be entitled to the $55,000 salary. However, Yash may have a right to restitution for any reliance damages he suffered due to his reliance on Yasmine's offer, such as expenses incurred from relocating.
