Answer:
He saves $0.0175 per mile
Step-by-step explanation:
Before the work done on the car´s engine, it took 0.033 gallons to travel one mile ( 5 gallons /150miles =0.033). After this work, the car spends 0.028 gallons to travel one mile (6 gallons/210 miles =0.028). The difference between this two is:
0.033 gallons/mile-0.028 gallons/mile= 0.005 gallons per mile.
Now Mr.Harper´s saves 0.005 gallons per mile.
In money he saves:
$3,50/gallon*0.005 gallon/mile= $0.0175/mile (the unit of "gallon" cancel each other)
Rounded to the nearest cent:
He saves $0.0 per mile.
