Answer 1

Let's go through each question one by one:

**Question 1:**
To find the total cost to fill up your tank, you can multiply the number of gallons pumped by the cost per gallon.
\[
\text{Total Cost} = \text{Gallons} \times \text{Cost per Gallon} = 22.35 \, \text{gallons} \times 1.79 \, \text{dollars/gallon} = 39.9515 \, \text{dollars}
\]
Rounding this to two decimal places gives you $39.95. However, if we look at the options, the closest match is \(\$40.01\). Thus, the answer for Question 1 is:
- **$40.01**

---

**Question 2:**
To calculate how much money you still owe after your friend gave you $31.56:
\[
\text{Amount Owed} = \text{Total Cost} - \text{Friend's Contribution} = 39.95 - 31.56 = 8.39
\]
Rounding this gives you about $8.39, but this isn't an option. However, one of the options might have a small rounding error depending on the total cost used. If you initially consider the answer obtained in Question 1, it could be considering a previous calculation. Based on the options given, the best answer is:
- **$8.45**

---

**Question 3:**
To find out how many miles you will drive if you do 1/4 of the trip:
\[
\text{Miles Driven} = \frac{448.6 \, \text{miles}}{4} = 112.15 \, \text{miles}
\]
The correct answer for Question 3 is:
- **112.15 miles**

To summarize:
1. **$40.01**
2. **$8.45**
3. **112.15 miles**
