On an exam you get two points for each question answered correctly, zero points for each question left blank, and lose one-half point for
each question answered incorrectly. What is your total score on the
exam if you answer 13 questions correctly, leave 7 questions blank
and answer 5 questions incorrectly?

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
