How many miles was the taxi ride?

Arun took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4 plus $4.25 per mile. The total fare was $110.25, not including the tip. How many miles was the taxi ride?

---

Total price = pick-up fee + price per mile times the number of miles

x = number of miles

110.25 = 4 + 4.25x
106.25 = 4.25x  {subtracted 4 from each side}
x = 25  {divided each side by 4.25}

the ride was 25 miles
