You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.

For any quadratic functions, ax² + bx + c, we can easily find the x-coordinate of its vertex through the use of the formula below.

x_{vertex} = \frac{-b}{2a}

where a and b are the coefficients of the function. For f(x), we have a = -1 and b = -16. Thus, we have
 
x_{vertex} = \frac{-16}{2(-1)}
x_{vertex} = 8

Since we now have the x-coordinate of the vertex, we can just easily substitute 8 into f(x) as shown below.

y_{vertex} = f(8) = -(8)+16(8)-60
y_{vertex} = 60

Thus, the vertex of f(x) is (8, 60). The vertex of the function shows the maximum value that the function can reach. For this particular case, the vertex represents the maximum profit that the shop owner could earn.

The x-intercepts of the function are the values of x when f(x) is zero. By equation f(x) with zero, we can solve the quadratic equation to find the x-intercepts as shown below.

-x^{2}+16x-60 = 0
x^{2}-16x+60=
(x-6)(x-10) = 0
x = 6
x=10

From this, we can see that the x-intercepts are (6, 0) and (10, 0). We just discussed that the x-intercepts are the values of x when y is zero. So, for this case it means that the shop does not earn a profit if they sell 6 or 10 candles. Basically, the x-intercepts represent the number candles sold if the shop wants to break even.
