Answer: 6 miles
Explanation:
From the question, we are informed that the taxi charges $4.75 for the first mile, and then $2.25 for each mile after that and that the total charge is $18.25.
The distance of Sara's taxi ride to the movie would be:
4.75 + 2.25m = 18.25
where,
m = number of miles
4.75 + 2.25m = 18.25
2.25m = 18.25 - 4.75
2.25m = 13.5
m = 13.5 / 2.25
m = 6 miles
The answer is 6 miles.
