Answer

### 65 chairs and 0 sofas

Explanation

## Step 1: Defining Variables and Setting up the Objective Function### Let be the number of chairs produced and be the number of sofas produced. The objective is to maximize income, which is given by the function .## Step 2: Setting up the Constraints### The production is limited by the available resources. Wood constraint: . Foam rubber constraint: . Fabric constraint: . Also, and since we cannot produce negative quantities.## Step 3: Simplifying the Constraints### Divide the wood constraint by 30: . Divide the foam rubber constraint by 7: . Divide the fabric constraint by 6: .## Step 4: Graphing the Constraints and Finding the Feasible Region### Plot the lines , , , , and . The feasible region is the intersection of all these inequalities. The vertices of the feasible region are , , , , and .## Step 5: Evaluating the Objective Function at Each Vertex### . . . . .## Step 6: Determining the Maximum Income### The maximum income is x=65 y=0$.
