Transcript text: Part 1 of 4 Points: 0 of 1 Save A firm will break even (no profit and no loss) as long as revenue just equals cost. The value of $x$ (the number of items produced and sold) where $C(x)=R(x)$ is called the break-even point. Assume that the below table can be expressed as a linear function. Find (a) the cost function, (b) the revenue function, and (c) the profit function. (d) Find the break-even point and decide whether the product should be produced, given the restrictions on sales. \begin{tabular}{|c|c|c|} \hline Fixed cost & Variable cost & Price of item \\ \hline$\$ 150$ & $\$ 20$ & $\$ 25$ \\ \hline \end{tabular} According to the restriction, no more than 26 units can be sold. (a) The cost function is $C(x)=$ $\qquad$ (Simplify your answer.)

Solution

Solution Steps

Step 1: Cost Function

The cost function is given by $C(x) = 150 + 20x$.

Step 2: Revenue Function

The revenue function is given by $R(x) = 25x$.

Step 3: Profit Function

The profit function is given by $P(x) = 25x - (150 + 20x) = 5x - 150$.

Step 4: Break-even Point

The break-even point is found by solving $C(x) = R(x)$, which gives $x = \frac{150}{5}$. Thus, the break-even point is at $x = 30$ units.

Step 5: Decision on Production

Given the restrictions on sales ($S = 26$), the product should not produce since the break-even point is greater than the sales restriction.

Final Answer:

The cost, revenue, and profit functions are defined as above with a break-even point at 30 units. Based on the given restrictions, the firm should not produce the product.
