Question

I keep on getting 240, helpp mee

Answer 1

First we need to figure out how much gas the car has in its tank so 3/4 of 12 is 9. Now we need to figure out an equation to use to solve this problem. 
Let x=distance

30/1.5=x

Multiply 30 and 1.5 by 6 because we have a 9 gallon tank.

180 miles for a 9 gallon tank. 

I think the best answer is D. because you can't really go more than you have in your tank. But you can go under and still have enough fuel to fill up.
