Hey there
Lets solve this question together,
Convert <span>76.8%</span><span> to a decimal.
</span>
Multiply 0.768<span> by </span>x<span> to get </span><span>0.768x</span><span>.
</span>
Multiply<span> each </span>term<span> by </span><span>1 / 0.768</span><span> and simplify.
</span>
Cancel the common factor of 0.768.
Divide 40.32<span> by </span>0.768<span> to get </span><span>52.5

Answer:
90 engines 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 minimum value of the function will happen for
C(x)=x²-180x+20,482
This means that
How many engines must be made to minimize the unit cost?
x value of the vertex. So
90 engines must be made to minimize the unit cost.
