2. a manager used a coordinate grid to place her employees in the office.
(a) what are the coordinates of each desk shown on the grid?
(b) which employee is the closest to the manager? justify your answer.

Idk if this is what you're looking for but...
Wendy's desk is at (-3,0)
Abu's desk is at (2,0)
Trey's desk is at (0,-4)
The Manager's desk is at (0,0) also known as the origin
Abu's desk is closest to the manager's desk because his desk is only 2 paces away from the managers on the x line

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
