The first company charges $40 per backpack and a $10 shipping fee for the order and the second company charges $38 per backpack and $16 shipping fee. How many backpacks would a customer need to order from either company so that the cost of the order was the same from both companies

3

Step-by-step explanation:

Multiply $40 by 3 then add 10 to get 130.

Multiply $38 by 3 then add 16 to get 130.

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.
