answer: ________ (round your answer to the nearest cent)

Explanation:

Step1: Calculate total gallons needed

First, find the number of gallons required by dividing total miles by miles per gallon.
$\frac{m}{g} = \frac{392}{28} = 14$

Step2: Calculate total gas cost

Multiply the number of gallons by the cost per gallon.
$3.65 \times 14$

Answer:

$\$51.10$
