Final answer:
The company is obligated to pay because Frank has performed the extra work.
Step-by-step explanation:
The correct answer is c. The company is obligated to pay because Frank has performed the extra work.
In this scenario, Frank has gone above and beyond his regular duties by promoting his employer's company on weekends. His boss acknowledges Frank's extra work and promises him a $1,000 bonus next month. This promise creates a legal obligation for the company to pay Frank the bonus.
The consideration (Frank's extra work) is not past consideration because it was done in reliance on the promise of the bonus. It is also not a preexisting duty because Frank was not already obligated to perform the extra work. Therefore, the company is obligated to pay Frank the bonus.
