Answer:
y = 1.00+0.10 x
Step-by-step explanation:
Considering there is a minimum charge of $1 up until they reach the point of 1/10 mile you would adds 0.10 for every additional 1/10 mile.
So if you were to say y was the charges and x is the no of 1/10 miles then the equation for y in terms of x would be:
y =1.00 +1/10(x)
y = 1.00+0.10 x
Then you just plug everything in. Hope this helped! :)
