The correct response is:
The Shaws’ trip is 225 miles and they’ve driven 175 miles.
This can be modeled by the equation \( d - 175 = 225 \), where \( d \) represents the total distance of the trip. In this case, if they have driven 175 miles and have a total trip distance of 225 miles, the remaining distance would be \( d - 175 = 225 \).
