Part 1) The system is solved using elimination

The cost  per can of grape juice is and the cost per can of apple juice is

Part 2) The system is solved using substitution

The cost  per can of grape juice is and the cost per can of apple juice is

Part 3) The system is solved by graphing

The graph in the attached figure

Step-by-step explanation:

Part 1) Solve the system by elimination

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

-----> equation A

 -----> equation B

Solve the system by elimination

Multiply the equation A by -6 both sides

-------> equation C

Multiply the equation B by 4 both sides

-------> equation D

Adds equation C and equation D

Substitute the value of x in the equation A

therefore

The cost  per can of grape juice is

The cost per can of apple juice is

Part 2) Solve the system by substitution

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

-----> equation A

-----> equation B

Substitute equation B in equation A and solve for x

Find the value of y

Substitute the value of x in the equation A

therefore

The cost  per can of grape juice is

The cost per can of apple juice is

Part 3) Solve the system by graphing

we have

-----> equation A

-----> equation B

Remember that

The solution of the system of equations is equal to the intersection point both lines

The solution is the point

see the attached figure

therefore

The cost  per can of grape juice is

The cost per can of apple juice is

1,918

step-by-step explanation:

if x = 1, then the answer is 3.5
