well from the info we deduce an equation out of this
so lets make y=total cost and x=# of miles
so because a towing company charges  80$ then 3$ ea. miles we can get this
y=80+3x
Ok now because Trini's car is 20 to 30 miles away we can't get a direct answer but we can get a range
so now we would sub in 20 and 30 into the equation and get the y values of 140 and 170
so your answer would be 140≤y≤170
