Both managers are paid a flat salary and are eligible for a bonus. The bonus is equal to 1 percent of their base salary for every 10 percent profit that exceeds a target. The maximum bonus is 5 percent of salary. Kevin's base salary is $320,000 and Michelle's is $380,000. The target profit for this year is $9 million.
