Milo offers George $300 to cook 500 tacos for him at an upcoming party. George accepts Milo's offer. The night before the party, George tells Milo that he got ripped off and will only cook 200 of the 500 tacos Milo intends to serve. Milo doesn't want his party ruined, so he offers George another $100 to stay and cook all 500 tacos. George agrees and makes 500 tacos, but the next day, Milo only pays the original $300. George sues for the additional $100. Will the court require Milo to pay the $100?

Yes, because Milo accepted George's offer to make all the tacos for $100 more

No, because George had a pre-existing duty to make all 500 tacos

Yes, because the additional $100 was valid consideration for George's taco making

No, because the parties never formed a contract
