Question

It costs Harry twice as much to fill the gas tank of his car while crossing over the mountain as it does if he waits to fill it after he has gone all the way over the mountain. Ultimately, he fills his gas tank once while crossing over the mountain and once after he gets all the way across the mountain, the total of which costs him $72. What is the cost of gas going over the mountain?

Answer 1

Are there answers to choose from?

Answer 3

Do you understand how I got the equation?

Answer 4

yeah i guess

Answer 5

Let x be the cost of gas.

Halfway= 2x
All the way= x

Cost of gas going over the mountain.
2x=72

Solve for x.

Answer 6

I just reread the question.

Answer 7

So basically, it's telling you that this guy, he's driving over a mountain and he can choose to refill at two stops. Once in the middle of his journey, or once after he has gone over the mountain. The question now wants to know what the cost of gas is.

Answer 8

to go over the mountain.

Answer 9

the question mentions that he fills gas once, halfway and then another time AFTER crossing the mountain.

Answer 10

so now, you only want to find how much it costed him to refill halfway, therefore the 2x=72. Do you know how to solve this?
