Answer:
20.9, rounded answer: 21 miles
Explanation:
x= distance between the airport and Ann's home.
since Ann is paying $2.10 per mile let 2.10 be the coefficient
our equation:
5 is our constant since that's how much Ann trips the driver
since the total is equal to 49.10, that's what our equation will be equal to
2.10x+5=49.10
sub "5"
2.10x+5-5=49.10-5
2.10x=44
divide both sides by "2.10"
2.10/2.10x=44/2.10
x=20.9
we can round 20.9 to 21
