Ashton Johnson · Answer 1

4x + 160y = 120

and

1x + 240y = 80

that will be be the equations. if we multiply the bottom equation by 4 we get:

4x + 960y = 320

now subtract one equation from another:

4x + 160y = 120

- (4x + 960y = 320)

and get:

-800y = - 200

y = $0.25

now plug this into one equation

x + 240 (.25) = 80

x + 60 = 80

x = $20

so $20 per day and $0.25 per mile
