Answer: Richard.
Step-by-step explanation: The question mark for Steve is 55, making the rate of change 110/2 or 55/1, or 1.
Geeta's pay's function is p=75+45h, and 75+45×1=120, 75+45×2=165, and 75+45×3=210. The rate of change for Geeta is 45/1, or 45.
Now, Richard's pay is easy. All u have 2 do is subtract 110-80=30, and subtract 80-50=30. His rate of change is 30/1, or 30.
