Will planned a $2-$week vacation in Florida to escape the winter cold. While speaking with his neighbor, Tim,

Will said to Tim "I will pay you $$50$ to shovel my driveway for each time that it snows while I am gone."

Will's flight is cancelled due to a category $3$ hurricane heading towards Florida's eastern coast. The next

day a foot of snow falls at Will's house, so Tim heads over and starts to dig out the driveway. When Tim is

nearly done with the job, Will sees him, runs outside and tells Tim not to bother, and revokes his original

offer. When Tim asks for payment for the work he had done, Will refuses. Which of the following is true?

Tim is not entitled to payment because a bilateral contract was involved that could only be accepted by full

performance.

Tim is entitled to recover the full $$50$ because he substantially completed shoveling the driveway.

Will cannot terminate the contract, so he is liable for any shoveling Tim does for the entire two weeks.

Will is not required to pay because the contract was illusory.
