A chain saw requires 2 hours of assembly and a wood chipper 6 hours. A maximum of 24 hours of assembly time is available. The profit is $150 on a chain saw and $240 on a chipper. How many of each should be assembled for maximum profit? To attain the maximum profit, assemble....... chain saws and ............wood chippers.

Answer:

To attain the maximum profit, assemble 9 chain saws and 1 wood chipper.

Explanation:

To find the number of chain saws and wood chippers that should be assembled for maximum profit, we can set up a linear programming problem.

Let's assume x represents the number of chain saws to be assembled, and y represents the number of wood chippers to be assembled.

We have the following constraints:

1) Assembly time constraint: 2x + 6y ≤ 24 (maximum of 24 hours of assembly time available)

2) Non-negativity constraint: x ≥ 0, y ≥ 0 (we cannot have negative quantities)

We want to maximize the profit, which is given by the objective function:

Profit = 150x + 240y

To solve this linear programming problem, we can use graphical or algebraic methods. Here, we will use algebraic methods.

First, let's graph the feasible region determined by the constraints:

The assembly time constraint can be rewritten as:

2x + 6y ≤ 24

x + 3y ≤ 12

y ≤ (12 - x)/3

Next, we plot the boundary lines and shade the feasible region:

Feasible region:

x ≥ 0 (non-negativity constraint)

y ≥ 0 (non-negativity constraint)

y ≤ (12 - x)/3 (assembly time constraint)

Based on the graph, we can see that the feasible region is a triangular region bounded by the x-axis, y-axis, and the line y = (12 - x)/3.

To find the vertices of this feasible region, we can solve the equations:

x = 0

y = 0

y = (12 - x)/3

Solving these equations, we find the vertices:

(0, 0)

(0, 4)

(6, 0)

(9, 1)

Now, we evaluate the objective function (Profit = 150x + 240y) at each vertex to determine the maximum profit:

At (0, 0): Profit = 150(0) + 240(0) = 0

At (0, 4): Profit = 150(0) + 240(4) = 960

At (6, 0): Profit = 150(6) + 240(0) = 900

At (9, 1): Profit = 150(9) + 240(1) = 1,710

The maximum profit is attained at (9, 1), which means assembling 9 chain saws and 1 wood chipper will result in the maximum profit.

To attain the maximum profit, assemble 9 chain saws and 1 wood chipper.
