Answer:
The minimum unit cost is 5377
Step-by-step explanation:
Note that we have a cudratic function of negative principal coefficient.
The minimum value reached by this function is found in its vertex.
For a quadratic function of the form
the x coordinate of the vertex is given by the following expression
In this case the function is:
So:
Then the x coordinate of the vertex is:
So the minimum unit cost is:
There are 10 marks between 7 and 8, therefore each mark is equivalent to 0.1
For 8.3, count 3 marks after 8:
First convert the fraction into decimal. Then count 6 marks from 7:
