Answer:
The total cost is D) $141
Step-by-step explanation:
To solve we can use the equation: 
d= number of days m= number of miles
We know both of these values so we can plug them in and solve.
y= 25(3) + 0.10(660)
y= 75 + 66
y = 141
F(x) = 3x-6
g(x) = x-2
so f/g = 3(x-2)/(x-2) = 3
hope this will help you
Your answer would be 14 meters
