First, determine the 6% of the given base price, $8.50 by multiplying this base price to the decimal equivalent of 6%.
                          $8.50 x 0.06 = $0.51
Add this amount to the base. That is,
                             $8.50 + $0.51 = $9.01
Hence, the total cost would be $9.01.

Which quadratic inequality does the graph below represent?​
Alja [10]

Answer:

y\leq 2x^2-8x+3

Step-by-step explanation:

we know that

The quadratic function of the figure has a vertex at (2,-5) and the y-intercept is the point (0,3)

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^2+k

where

(h,k) is the vertex

a is a coefficient

we have

(h,k)=(2,-5)

substitute

y=a(x-2)^2-5

with the y-intercept find out the value of a

For x=0,y=3

3=a(0-2)^2-5

3=4a-5

4a=8

a=2

The equation is

y=2(x-2)^2-5

y=2(x^2-4x+4)-5

y=2x^2-8x+8-5

y=2x^2-8x+3

Looking at the graph, the solution is the shaded area below the quadratic equation

so

the value of y must be less than or equal to the quadratic function

y\leq 2x^2-8x+3
