I have a math test tomorrow but i have no idea how to do what we're doing. someone please help me- I'm a 7th grader doing 8th grade math and my head is on the verge of exploding-

Is there specific topic/topics you are working on?

Also, if you are struggling Khan Academy has some informative videos all you have to do is search up a topic on their site and a video will come up with practice questions to try after the video as well!

good luck on your test!!

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
