If the price of a pair of shoes is $35.00 before tax, and tax is 20%, what will the final price of the pair of shoes be?

$42 will be the final price of the pair of shoes

Step-by-step explanation:

As per the statement:

If the price of a pair of shoes is $35.00 before tax, and tax is 20%,

⇒Price of a pair of shoes  before tax = $35

Tax = 20%

Sales tax price =

We have to find the final price of the pair of shoes be.

Final price after tax = price before tax+ sales tax price = $35 + $7 = $42

Therefore, $42 will be the final price of the pair of shoes

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.
