To solve this problem, we need to determine two things:

1. The amount of gasoline required to drive 440 miles.
2. The total cost of the gasoline needed.

Step 1: Calculate the amount of gasoline required

You know that your car gets 29 miles per gallon (mpg). To find out how many gallons of gasoline are needed to drive 440 miles, use the following formula:

$\text{Gallons needed} = \frac{\text{Total miles driven}}{\text{Miles per gallon}}$

$\text{Gallons needed} = \frac{440 \text{ miles}}{29 \text{ mpg}} \approx 15.17 \text{ gallons}$

Step 2: Calculate the total cost of the gasoline

Now, multiply the number of gallons by the cost per gallon:

$\text{Total cost} = \text{Gallons needed} \times \text{Cost per gallon}$

$\text{Total cost} = 15.17 \text{ gallons} \times \$2.80/\text{gallon} \approx \$42.48$

Conclusion

The cost to drive 440 miles when gasoline costs $2.80 per gallon is approximately $42.48.
