15 points she scores on a quiz were only 60%

I do not really understand this question however what i can understand from it is that for each question answered correct you will gain 4 points so if you got 15 questions 15*4=60 and there are 25 total questions.

Step-by-step explanation:

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
