Allegheny County

Step-by-step explanation:

6% (or 0.06) of $24.99 is $1.50 (see example below)

7% (or 0.07) of $24.99 is $1.75

Example: 0.06 x 24.99 = 1.4994 or rounded off would equal 1.50

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

answer: 0.1,0.85
