Answer:
12y+4x
Step-by-step explanation:
Multiply 4*3y and 4*x
Distributive property
You can solve for x and y in terms of z, then let z take on the value of the parameter.
Subtracting the first equation from the second, you get
... x_2 +x_3 = 1
Subtracting that from the first equation gives you
... x_1 +2x_3 = 3
Let x_3 = t. Then your parametric equations are ...

So there’s 2 people, each getting 24.28. Multiply 24.28 by 2 to get $48.56
