Answer :
The price should be, to the nearest cent, to make the maximum profit is 775.34.
What is the price the widgets should be sold for?
This is a quadratic equation and if you were to graph this you would see that it is a parabola that opens down because of the negative leading coefficient (-3).
The maximum profit would be at the vertex, of the graph. Therefore, we need to find the value of "y" when "x" is the line of symmetry. We find this by x=-b/(2a) where a = -3 and b = 152:
x=-152/(2)(-3)
x=-152/-6
x=152/6
We put this value of "x" into the original formula to find out the value of "y":
y=-3x2+152x-1150
y=(-3)(152/6)2+152(152/6)-1150
y=-1925.33+3850.67-1150
y=775.34
Therefore, the maximum profit would be 775.34.
