Answer:
To determine how much fuel Deon used, we can subtract the amount of fuel left from the initial amount of fuel.
Deon's car initially had 16.14 gallons of fuel, and now there are 1.7 gallons left. Therefore, the amount of fuel used can be calculated as:
16.14 gallons - 1.7 gallons = 14.44 gallons
Deon used approximately 14.44 gallons of fuel.
