Answer:
10 miles
Step-by-step explanation:
Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:
$6 = $0.75x + $2.25
$6 = the total amount of the trip
$0.75 = the cost for each mile after the initial 5 miles
$2.25 = the flat fee for the first 5 miles
Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x
Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles
Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
