Sara needs to take a taxi to get to the movies. The taxi charges $4.75 for the first mile, and then $2.25 for each mile after th
Papessa [141]

Answer: 6 miles

Step-by-step 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.

The range of the following set of data is 170, 130, 100, 110, 150, 200, 120
Dmitry_Shevchenko [17]

Since range is the difference between the highest and lowest value, simply subtract 100 from 200.

200 is the highest value in this set and 100 is the lowest value in this set.

Final answer is 100.

Range = 100
