Asked by Shelby
An aircraft factory manufactures airplane engines. The unit cost
C
(the cost in dollars to make each airplane engine) depends on the number of engines made. If
x
engines are made, then the unit cost is given by the function
=Cx+−0.2x248x21,748
. What is the minimum unit cost?
Do not round your answer.

C appears to be a quadratic. As with any quadratic
ax^2+bx+c
the vertex lies at x = -b/2a
So, find C(x) at that value.
