Answer:
Employee C
Explanation:
To find what you need you need to divide the total number they got in total to the number in the front.
For employee A, you would do 180/15 and that would give you 12.
For employee B, you would do 210/20 and that would give you 10.5.
For employee C, you would do 455/35 and that would give you 13.
That would make employee C have the highest earnings per hour.
