The cost in dollars, C, to manufacture n necklaces is given by the equation C(n) = an + b, where a and b are positive constants. In this equation, what does a represent?
  • a)
    the fixed costs, in dollars, independent of any necklaces being manufactured
  • b)
    the total cost, in dollars, to produce n necklaces, not including fixed costs
  • c)
    the total cost, in dollars, to produce one necklace, including fixed costs
  • d)
    the cost, in dollars, to produce one necklace, not including any fixed costs
Correct answer is option 'D'. Can you explain this answer?

C(n) = an + b
Since this expression is linear in n (the input variable, which represents the number of necklaces produced), the constant a represents the slope of this line, which in turn represents the “unit rate of increase,” in other words, the increase in total cost for each individual necklace produced.
The constant b represents the “y-intercept” of this line, which in this case means the costs when n = 0 (that is, the fixed costs before any necklaces are produced).

Explanation:

Cost Equation:
- The given equation C(n) = an + b represents the cost in dollars to manufacture n necklaces, where a and b are positive constants.

Interpretation of 'a':
- 'a' represents the cost, in dollars, to produce one necklace, not including any fixed costs.
- This means that 'a' is the variable cost per necklace, which increases as more necklaces are produced.

Fixed Costs:
- Fixed costs are constant costs that do not change with the number of necklaces produced.
- In the given equation, the term 'b' represents the fixed costs, in dollars, independent of any necklaces being manufactured.

Understanding the Cost Equation:
- When n = 0 (producing zero necklaces), the cost C(0) = 0a + b = b.
- This shows that the fixed costs 'b' are incurred even when no necklaces are produced.
- As the number of necklaces produced increases (n > 0), the total cost includes both the fixed costs and the variable costs per necklace.

Conclusion:
- Therefore, in the cost equation C(n) = an + b, 'a' represents the cost, in dollars, to produce one necklace, not including any fixed costs.
