Answer: In Favour of Ewing.
Step-by-step explanation:
When Dean made that promise, he got into a contract with Ewing.
Now for a contract to be enforceable, 4 components must be satisfied. These components are, Agreement, Capacity (mental), Consideration and Legality.
From the above text we can tell that this is therefore a valid contract because both of them agreed to the proposal and were both of sound mind when they did. There was a Consideration ( the benefit in the contract) of $10 per pound and this contract is legally sound so this is a valid contract.
Ewing has fulfilled his side of the bargain and is entitled to his reward or payment.
Dean's claim that Ewing’s improved health is a sufficient benefit for his effort and sacrifice which indeed is a benefit, should not be considered sufficient because it was not agreed upon as a term in the contract.
