Answer:
44.10 = 2.1x
x = 21 miles
Step-by-step explanation:
Cost per mile = $2.1
Driver tip = $5
Total amount paid = $49.10
Let
x = number of miles
Write an equation to determine the distance in miles \left(x\right)(x) between the airport and Anna's home.
Total cost of miles = Total amount paid - Driver tip
= $49.10 - $5
= $44.10
Equation to determine distance in miles
Total cost of miles = cost per mile * number of miles
44.10 = 2.1x
Find the distance between the airport and Anna's home
44.10 = 2.1x
Divide both sides by 2.1
44.10 / 2.1 = 2.1x / 2.1
21 = x
x = 21 miles
