1 answer:
Since you need the vertex, and knowing the vertex will tell you the axis of symmetry, it is convenient to put the equation in vertex form.
.. -x^2 -4x +1
.. = -(x^2 +4x) +1
.. = -(x^2 +4x +(4/2)^2) +1 -(-(4/2)^2) . . . . complete the square
.. = -(x +2)^2 +5
The vertex is (-2, 5).
The axis of symmetry is x = -2.
.. -x^2 -4x +1

Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is
where is the amount of money and
is the number of hours.
Since can be at most 8, this is the case that generates the highest money, so if we plug
we have
