Final answer:
Carmen used 26.13 gallons of fuel, calculated by subtracting the remaining fuel (2.9 gallons) from the original fuel amount (29.03 gallons).
Step-by-step explanation:
The student asked how much fuel Carmen used if her car had 29.03 gallons of fuel in the morning and now has 2.9 gallons. To calculate the amount of fuel used, we subtract the current amount of fuel from the original amount.
Here's the step-by-step calculation:
- Start with the original amount of fuel: 29.03 gallons.
- Subtract the remaining amount of fuel: 2.9 gallons.
- The difference is the amount of fuel used.
Therefore:
29.03 gallons - 2.9 gallons = 26.13 gallons
Carmen used 26.13 gallons of fuel.
