I cant see the picture. So sorry i cant help
The equation set up is:
0.5x² - 40x + 15300 = 0
Cost, C(x) = 35x + 300
Revenue, R(x) = 75x - 0.5x²
Profit, P(x) = 15000
Profit = Revenue - Cost
P(x) = R(x) - C(x)
15000 = 75x - 0.5x² - (35x + 300)
15000 = -0.5x² + 40x - 300
0.5x² - 40x + 15000 + 300 = 0
The quadratic equation to get the number of items sold is shown below:
0.5x² - 40x + 15300 = 0

No graph has been provided, but I've provided the graph shown below. Recall that the slope intercept form of the equation of a line is given by:
First of all, the y-intercept of this graph lies on the point:
So our correct option could be either B) or C) because the y-intercept in those cases lies also on the point . If you lies on this point and walk 1 units horizontally, then the y-coordinate runs 3 units up until it gets point . Therefore, the slope of this line is
In conclusion, this graph is represented by the equation:
B) y = 3x + 1
Call x the number of children.
originally each got $240/x
but later one part was redistributed so each of the (x-1) children got $240/(x-1).
We also know that $240/(x-1) = $240/x + $8. that is our equation to solve for x.
240x = 240*(x-1)+8x(x-1)
240x = 240x - 240 + 8x^2 - 8x
8x^2 - 8x - 240 = 0
this is a quadratic equation with two solutions. you get the solutions using a formula (of your preference). On my end I got the two solutions as x1=-5 and x2=6.
Clearly the solution (number f children) can't be negative, so the one practical solution is x=6 which is the number of children in the Kind family.
A, b, c, D let me know if this helps
