Math Problem Statement

Superbats Inc. manufactures two different types of wood baseball bats, the Homer-Hitter and the Big Timber. The Homer-Hitter takes 8 hours to trim and turn on the lathe and 2 hours to finish. Each Homer-Hitter sold makes a profit of $17. The Big Timber takes 5 hours to trim and turn on the lathe and 5 hours to finish, and its profit is $29. The total time available for trimming and lathing is 80 hours. The total available time for finishing is 50 hours.

Solution

This problem is about optimizing the production of two types of bats, Homer-Hitter and Big Timber, to maximize profit while considering the available hours for trimming, lathing, and finishing. We can set it up as a linear programming problem. Let's define the variables and constraints.

Variables:

  • Let xx be the number of Homer-Hitter bats produced.
  • Let yy be the number of Big Timber bats produced.

Objective Function:

The goal is to maximize the total profit, which can be expressed as: Maximize P=17x+29y\text{Maximize } P = 17x + 29y Where:

  • Profit per Homer-Hitter bat = $17
  • Profit per Big Timber bat = $29

Constraints:

  1. Trimming and lathing constraint: The total time available for trimming and lathing is 80 hours. The Homer-Hitter takes 8 hours, and the Big Timber takes 5 hours. 8x+5y808x + 5y \leq 80

  2. Finishing constraint: The total available time for finishing is 50 hours. The Homer-Hitter takes 2 hours to finish, and the Big Timber takes 5 hours. 2x+5y502x + 5y \leq 50

  3. Non-negativity constraint: The number of bats produced cannot be negative. x0,y0x \geq 0, \quad y \geq 0

Linear Programming Model:

Maximize: P=17x+29yP = 17x + 29y

Subject to: 8x+5y808x + 5y \leq 80 2x+5y502x + 5y \leq 50 x0,y0x \geq 0, \quad y \geq 0

This forms a standard linear programming model. The next step would be to solve this system either graphically (by plotting the constraints) or using a method like the Simplex algorithm to find the optimal values for xx and yy.

Would you like me to solve this graphically or numerically? Alternatively, I can explain the Simplex method if you're interested.

Tip:

In linear programming problems, always check the feasibility of the constraints before solving to ensure that the problem can have a solution.
