Answer:
$1,350 per month
Step-by-step explanation:
The reason is that the damage due to breach of the contract is always compensated and the damage caused by the breach of the company in this case is $1,350 ($4,500 - $3,500 + $350).
So the company is liable to compensate Rita for its breach of contract and the amount that it will compensate to Rita would be $1350 per month till the agreed time of contract to keep Rita for $4500.
