The equation \( d - 175 = 225 \) can be interpreted as follows:
- \( d \) represents the total distance of the trip.
- The equation states that if you subtract the distance already driven (175 miles) from the total distance (\( d \)), you are left with 225 miles remaining.
Thus, the correct real-world scenario modeled by this equation is:
The Shaws’ trip is 225 miles and they’ve driven 175 miles.
