Problem
2. You plan to drive to a resort that is 399 miles away. Your car presently gets 28 miles per gallon. How many gallons of gas will it take you to get to the resort? If gas is currently \( \$ 2.45 \) per gallon, how much will it cost you to drive to the resort and back home?
Solution
Step 1 ：\( \text{Total miles} = 2 \times 399 = 798 \)
Step 2 ：\( \text{Gas needed} = \frac{798}{28} = \frac{399}{14} \) gallons
Step 3 ：\( \text{Cost} = \frac{399}{14} \times 2.45 \times 2 = \$ 139.29 \)
