Astore advertises 15% off an ítem that regularly sells for $300. what is the sale price of the item?

$255

Step-by-step explanation:

To find amount that is subtracted off of the original price, you would need to multiply 300 by 15% as a decimal

The decimal form of 15% is 0.15, meaning that you would have to multiply 300 and 0.15

Once you do this, you will get 45

To find the sale price, you need to subtract the amount that is discounted, 45, from 300

Once you do this, you will get 255

This means that the sale price of the item is $255

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.
