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:
- $40.01
- $8.45
- 112.15 miles
