Ann took a taxi home from the airport. the taxi fare was $2.10 per mile, and she gave the driver a tip of $5. ann paid a total of $49.10. write an equation to determine the distance in miles (x) between the airport and ann's home. find the distance between airport and ann's home.

Write an equation to determine the distance in miles (x) between the airport and Ann's home: 2.1x + 5 = 49.10

Find the distance between the airport and Ann's home: 21 miles

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
