Mix some of the $5.50 per pound with 100 pounds of $6.25 per pound to get a $6 per pound mix

x lbs * 5.5 + 100 lbs * 6.25 = (x+100) * 6.00

distribute

5.5x + 625 = 6x+600

subtract 5.5 x from each side

625 = .5x +600

subtract 600 from each side

25 = .5x

divide each side by .5

x = 100

You need 100 pounds of the 5.50 mix

answer: 590

step-by-step explanation:

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.
