A chili recipe calls for 2 pounds of ground pork and 3.5 pounds of ground beef. The cost of ground beef per pound is $0.20 less than twice the cost of ground pork. If the total cost of meat for the recipe is $15.05, what is the cost per pound of ground pork?

$1.87

Step-by-step explanation:

Given the amount of ground pork =2 pounds and

the amount of ground beef =3.5 pounds.

Let the cost of ground pork= $x per pound

So, the cost of the 2 pounds pork = $2x

As the cost of ground beef per pound is $0.20 less than twice the cost of ground pork, so

the cost of ground beef =$ 2x-0.20 per pound

So, the cost of 3.5 pounds ground beef =$ 3(2x-0.20)

Total cost of meat = $15.05

Hence, the cost of ground pork= $1.87 per pound

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

i think the answer is d im not sure
