Answer:
300 cars must be made to minimize the unit cost
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
It's vertex is the point
In which
Where
If a>0, the vertex is a minimum point, that is, the minimum value happens at , and it's value is
.
The cost of producing x cars is given by:
So a quadratic equation with
How many cars must be made to minimize the unit cost?
This is the xvalue of the vertex. So
300 cars must be made to minimize the unit cost
