Introduction

Tim owns a clothing store where he designs pairs of shorts and T-shirts. He sells the shorts for $12 each and the T-shirts for $8 each. Tim can work a maximum of 18 hours a day. It takes him 2 hours to design a pair of shorts and 1 hour to design a T-shirt. The goal is to maximize the profit by determining the optimal number of pairs of shorts and T-shirts to produce each day.

Mathematical Model

Let's denote the number of pairs of shorts produced as x and the number of T-shirts produced as y. The profit function can be represented as:

P(x, y) = 12x + 8y

The objective is to maximize the profit function subject to the constraints:

  • 2x + y ≤ 18 (production constraint)
  • x ≥ 0 (non-negativity constraint for shorts)
  • y ≥ 0 (non-negativity constraint for T-shirts)

Linear Programming Formulation

The problem can be formulated as a linear programming problem:

Maximize P(x, y) = 12x + 8y Subject to: 2x + y ≤ 18 x ≥ 0 y ≥ 0

Graphical Method

To visualize the problem, we can use a graphical method. The production constraint 2x + y ≤ 18 can be represented as a line in the xy-plane. The feasible region is the area below and to the left of this line.

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 9, 100)
y = 18 - 2 * x



plt.plot(x, y, label='Production constraint')



plt.title('Production Constraint')
plt.xlabel('x (shorts)')
plt.ylabel('y (T-shirts)')



plt.show()

Solving the Problem

To solve the problem, we can use the graphical method or the simplex method. The graphical method involves finding the feasible solution that maximizes the profit function.

import numpy as np
import matplotlib.pyplot as plt


def profit(x, y):
return 12 * x + 8 * y



x = np.linspace(0, 9, 100)
y = 18 - 2 * x



max_profit = 0
max_x = 0
max_y = 0
for i in range(len(x)):
if x[i] >= 0 and y[i] >= 0:
current_profit = profit(x[i], y[i])
if current_profit > max_profit:
max_profit = current_profit
max_x = x[i]
max_y = y[i]



print('Optimal solution:')
print('x =', max_x)
print('y =', max_y)
print('Profit =', max_profit)
