Final answer:
To determine if Juan breached the contract, it is necessary to analyze the terms of the agreement. If the promised extra vacation week was not specified in the contract, Juan may argue that he did not breach the contract by denying Henry the additional time off.
Step-by-step explanation:
In order to evaluate whether Juan breached the contract by denying Henry the promised extra vacation week, we need to analyze the terms of the contract.
Based on the provided information, Henry entered into an agreement with Juan where he was allowed to hire his own time and pay Juan three dollars at the end of each week. In return, Henry was to provide his own calking tools and cover his expenses for board and clothing.
The contract does not explicitly mention an extra vacation week. Therefore, if the promised extra week was not specified in the contract, Juan may argue that he did not breach the contract by denying Henry the additional time off.
