Answer:
The correct option is a.
Step-by-step explanation:
The average cost function is
Where x is the number of calendars produced.
The average cost formula is
Therefore the total cost is defined b the function
Here 600 is the initial cost and the cost each unit is 2.
Initial cost is the fixed cost which occurs at zero level of productivity.
The company spends $600 on a new computer and printer before beginning the project. The option (a) is correct.
The step in which Yvonne first makes an error while solving the quadratic equation by completing the square in step 1.
<h3>What is a quadratic equation?</h3>A quadratic equation is an equation in which the highest power of the variable is two.
Yvonne is solving the quadratic equation, which is,
6x² +24x +7 =0
He is solving the above equation by completing the square.
The first step to solving this quadratic equation by completing the square is, Take the constant value 7 at the opposite side of the equation as,
6x² +24x = -7
Here, the number seven was a positive number, which we have changed to negative because this number brings the other side of the equation.
In the image attached below, the first step of the Yvonne while solving the equation by completing the square is,
6x² +24x = 7
Here, Yvonne does not change the sign of the number 7 while taking it to another side of the equation.
Hence, the step in which Yvonne first makes an error while solving the quadratic equation by completing the square is step 1.
