Post one question at a time.

The amount of revenue made in Company XYZ is predicted to make follows the mathematical model y = 20.5x-5000, where y is the amount of revenue, and x is the number of employees.

I will solve part (a) only.

(a) How much revenue is estimated if there are 200 employees in the Company? 

Replace x with 200 and solve for y.

y = 20.5(200)- 5000

y = 4100 - 5000

y = -900
