Answer:
Step-by-step explanation:
Let x be the distance driven, d-distance and C our constant.
Our information can be presented as:
#Subtracting equation 2 from 1:
Hence the fixed cost per mile driven, is $0.20
To find the constant, we substitute
in any of the equations:
Now, substituting our values in the linear equation:
#y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284
