The amount of profit made = y
The selling price of each widget = x
The equation representing the relationship between x and y is:
[tex]y=-29x^2+1388x-10040[/tex]Find dy/dt
[tex]\frac{dy}{dx}=\text{ -58x + 1388}[/tex]Find the value of x at which dy/dx = 0
0 = -58x + 1388
58x = 1388
x = 1388/58
x = 23.93
Substitute x = 23.93 into the equation given:
