Answer: $3.25
Step-by-step explanation:
First you need to calculate the cost of the 8 pounds of nuts.
Cashews = 4 x $4 = $16
Peanuts = 4 x $2.50 = $10
The total cost of 8 pounds of nuts equals $16 + $10 = $26
In order to calculate the cost of 1 pound of the mixture you need to divide the total cost by the total weight.
$26 / 8 lbs = $3.25 / lb
The cost of one pound of the mixture is $3.25.

Answer:
Step-by-step explanation:
The point-slope formula is 
. When knowing the slope of a line and a point it intersects, we can write its equation with that formula. Substitute 
, 
, and 
for real values.
1) First, find , or the slope. Use the slope formula 
and substitute the x and y values of the given points. Then, solve:
Therefore, the slope of the line is -10.
2) Now, substitute the needed real values into the point-slope formula, . Since represents the slope, substitute -10 in its place. Since and represent the x and y values of a point the line crosses, choose any of the points given and substitute its values into the formula. (Either one is fine, they both equal the same thing. I chose (2,3).) This will give the following answer and equation:
