Part 1

A firm manufactures a product that sells for

​$2525

per unit. Variable cost per unit is

$ 7$7

and fixed cost per period is

$ 1440.$1440.

Capacity per period is

12001200

units.

​(a) Develop an algebraic statement for the revenue function and the cost function.

​(b) Determine the number of units required to be sold to break even.

​(c) Compute the​ break-even point as a percent of capacity.

​(d) Compute the​ break-even point in sales dollars.

Solution

Let's break down each part of the problem step by step:

Given Information:

  • Selling Price per Unit (Revenue per Unit) = $25
  • Variable Cost per Unit = $7
  • Fixed Costs per Period = $1,440
  • Capacity per Period = 1,200 units

Part (a): Develop the Revenue Function and the Cost Function

  1. Revenue Function:

    The revenue function R(x)R(x) represents the total revenue generated from selling xx units. Given that each unit sells for $25, the revenue function is:

    R(x)=25xR(x) = 25x where xx is the number of units sold.

  2. Cost Function:

    The total cost function C(x)C(x) consists of fixed costs and variable costs. The fixed cost is $1,440 per period, and the variable cost is $7 per unit. Thus, the cost function is:

    C(x)=1440+7xC(x) = 1440 + 7x where xx is the number of units produced and sold.

Part (b): Determine the Number of Units Required to Break Even

The break-even point occurs when total revenue equals total costs. This can be determined by solving the equation R(x)=C(x)R(x) = C(x).

25x=1440+7x25x = 1440 + 7x

Simplifying this equation:

25x7x=144025x - 7x = 1440 18x=144018x = 1440 x=144018=80x = \frac{1440}{18} = 80

So, the firm needs to sell 80 units to break even.

Part (c): Compute the Break-Even Point as a Percent of Capacity

The capacity is 1,200 units. To find the break-even point as a percentage of capacity:

Break-even percent=(801200)×100=6.67%\text{Break-even percent} = \left(\frac{80}{1200}\right) \times 100 = 6.67\%

Thus, the break-even point is 6.67% of the firm's capacity.

Part (d): Compute the Break-Even Point in Sales Dollars

The break-even point in sales dollars is the revenue generated at the break-even point, which can be calculated by multiplying the number of units at the break-even point by the price per unit:

Break-even sales=80×25=2000\text{Break-even sales} = 80 \times 25 = 2000

So, the break-even point in sales dollars is $2,000.


Summary of Results:

  • (a) Revenue function: R(x)=25xR(x) = 25x, Cost function: C(x)=1440+7xC(x) = 1440 + 7x
  • (b) Break-even units: 80 units
  • (c) Break-even point as a percent of capacity: 6.67%
  • (d) Break-even point in sales dollars: $2,000

Related Questions:

  1. What happens if the selling price per unit increases to $30?
  2. How would a change in fixed costs to $1,600 affect the break-even point?
  3. What if the variable cost increases to $10 per unit? How does it change the break-even point?
  4. Can you compute the profit if the firm sells 150 units in a period?
  5. How would a reduction in capacity to 1,000 units affect the break-even percentage?

Tip:

To minimize the break-even point, firms can either increase the selling price or reduce costs (fixed or variable).
