Y= -x^{2}+4x+6

Turning points occur when the gradient of the function is zero.
\frac{dy}{dx} =-2x+4
Then equating to 0;
-2x+4=0
-2x=-4
x=2

From the fucntion, when x=2 ;
y=-(2)^{2}+4(2) +6
y=-8+8+6
y=6
Turning point;
(2,6)

Profit = revenue - expenses

250 = 25x - (12x + 60)
250 = 25x - 12x - 60
250 = 13x - 60
250 + 60 = 13x
310 = 13x
310/13 = x
23.85 = x....so she would have to sell 24 purses
