For this case we have that by definition, the quadratic formula is:
A quadratic equation is of the form:
Option A: This equation can be solved without the quadratic formula
Option B:
This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.
Option C:
Similarly, this equation can be solved with the quadratic formula
Option D:
In this factored equation we can see that the roots are
Answer:
Option B, C
Given:
Fixed cost = b = $ 42,500
Production cost (Variable cost) /unit = m = $ 6/ unit
Let 'x' represent the number of unit, therefore the variable cost will be
a) The cost function will be the sum of the fixed cost and the variable cost.
b) The revenue function is the amount the product is sold per unit.
Recall: 'x' represents the number of units.
Therefore,
Hence, the revenue function R(x) is
c) The profit function is the difference between the revenue function and the cost function.
Hence, the profit function is
d) Let us compute the profit (loss) values when the units are 6000 and 11000
Using the profit function
Therefore,
Hence,
