Mia contracted with Greencare Lawn Service for a pest treatment on Mia's lawn for $$1,000.$ Pat lives next door to Mia.Greencare mistakenly treats Pat's lawn instead of Mia's. Pat watched them perform the treatment while looking through the window of his living room, but did not go outside and stop them. When Greencare seeks payment from Pat, Greencare can probably receive:$$1,000$ from Mia, because there was a contract.nothing, because Greencare's contract was with Mia, not Pat.from Pat an amount less than the contract amount that will reimburse Greencare for expenses incurred, in order to avoid unjust enrichment.$$1,000$ from Pat, because Pat received the full value of the service.Which one is correct $?$
