I need help solving this problem

ForeTech is a sporting equipment manufacturer that produces two different types of golf balls, the DriveMaster and the GreenHunter. The golf balls are manufactured in batches; each batch of the DriveMaster yields $10 profit, while each batch of the GreenHunter yields $6 profit. The golf balls are made using three separate processes: making the core of the ball, adding the middle layers, and coating with a synthetic resin. There is one machine for making the core and one for adding the middle layers; three machines are available for the coating process. Each machine can be operated for 10 hours per day. Both types of golf balls require 3 minutes per batch to make the core. Adding the middle layers takes 6 minutes per batch for the DriveMaster, but only 2 minutes per batch for the GreenHunter. The coating process takes 12 minutes per batch of DriveMaster and 9 minutes per batch of GreenHunter. Formulate a linear programming model to determine the optimal number of batches of each type of golf ball that ForeTech should produce, with the goal of maximizing profit.
