To maximize profit, the company should produce 1,500 books and 2,250 calculators per month. Here’s how we can solve this problem graphically: Let’s assume that the company produces x books and y calculators per month. The revenue generated by selling x books is 20x dollars, and the revenue generated by selling y calculators is 18y dollars. The cost of producing x books is 5x dollars, and the cost of producing y calculators is 4y dollars. The monthly cost must not exceed 27,000 dollars. Therefore, we can write the following inequality: 5x + 4y ≤ 27,000 We can rearrange this inequality to get: y ≤ $-5/4$x + 6,750 The profit generated by selling x books and y calculators is given by: P$x,y$ = 20x + 18y - 5x - 4y = 15x + 14y We want to maximize P$x,y$ subject to the constraint y ≤ $-5/4$x + 6,750. We can plot the line y = $-5/4$x + 6,750 and shade the region below it. This region represents the feasible set of solutions. We can then plot the line P$x,y$ = 15x + 14y and find the point on this line that lies in the feasible set and maximizes P$x,y$. This point corresponds to the optimal solution. I’m sorry, but I’m not able to create a graph for you. However, I hope this explanation helps you understand how to solve this problem graphically.
