Zero, Inc. agreed to build Millie a storage building for $8,000. After beginning the
project, Zero realized that it could not complete the job and make a profit. Zero
demanded $9,500 to complete the building. Millie agreed to pay the $9,500. When the
project was complete, Millie tendered $8,000 to Zero for the job. If Zero sues Millie for
the remaining $1,500:
a. Zero will win because there was consideration for the additional $1,500.
b. Zero will win because Millie had a pre-existing duty to pay any additional amounts.
c. Zero will lose because there was no legal consideration to support the additional
$1,500.
d. Zero will lose because the UCC does not require consideration to modify an existing
contract.
