Answer:
[tex]780\text{ miles}[/tex]
Step-by-step explanation:
Since Pamela's car's MPG (miles-per-gallon) is maintained, we can set up the following proportion:
[tex]\frac{234}{9}=\frac{x}{30}[/tex], where [tex]x[/tex] is the number of miles she can drive with 30 gallons of fuel.
Multiply both sides by 30:
[tex]x=\frac{234\cdot 30}{9},\\x=\boxed{780\text{ miles}}[/tex]
Therefore, Pamela can drive 780 miles with 30 gallons of fuel.
