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
Answer:
13,811 + 5 = 13816
13816 / 11 = 1,256
The number to add is 5

Answer:
80 (I think)
Step-by-step explanation:
I would just go to x=7 and look up until i reach the line of best fit. The intersection is at y=80
