Math Problem Statement
Suppose a company has fixed costs of $4000 and variable costs per unit of
15
16
x + 1270 dollars,
where x is the total number of units produced. Suppose further that the selling price of its product is
1400 −
1
16
x dollars per unit.
Find the break-even points. (Enter your answers as a comma-separated list.)
Solution
To find the break-even points, we need to set the total costs equal to the total revenue.
Given:
- Fixed Costs (FC) = $4000
- Variable Cost per unit (VC) =
- Selling Price per unit (SP) =
Total Cost (TC):
The total cost is the sum of fixed and variable costs:
Total Revenue (TR):
Total revenue is given by:
Setting TC equal to TR:
Expanding both sides:
-
Left Side:
-
Right Side:
Combining:
Rearranging:
Combine all terms on one side: This simplifies to:
Solving the Quadratic Equation:
Using the quadratic formula: where , , and .
Calculating the discriminant:
Calculating the roots: This gives us two solutions:
Break-even Points:
The break-even points are:
If you have any questions or need further details, feel free to ask! Here are some follow-up questions to consider:
- How would changes in fixed costs affect the break-even points?
- What impact do variable costs have on the overall profitability?
- How can the company increase its break-even sales?
- What strategies can be implemented if the selling price changes?
- How would a decrease in selling price affect the break-even analysis?
Tip: Always analyze how fixed and variable costs interact when assessing profitability!
