All employees with one or more years of service are eligible for a bonus. Pay Grade 1 employees receive $3,000 (cell U2), Pay Grade 2 employees receive $6,000 (cell U3), and Pay Grade 3 employees receive $8,000 (cell U4). In the Bonus column, use the IFS function to calculate the bonus. For employees in pay grades over 3, there is no bonus. (HINT: the AND function is used in the logical test within the IFS function because you have to test if the years of service >=1 AND each specific pay grade)
