Which of the following describes a situation for the inequality: 3w + 9 ≤ 21 A. A girl get $3 for every box of cookies sold plus 9 dollars for trying. She makes either $21 total or just below that amount.

B. A girl get $3 for every box of cookies sold plus nine dollars for trying. She makes either $21 total or more than that amount.

C. Girl scout cookies are good, just pay the girl! (this is not the correct answer.)

D. A girl get $9 for every box of cookies sold plus 3 dollars for trying. She makes either $21 total or just below that amount.

The answer would be A. A girl gets $3 for every box of cookies sold plus 9 dollars for trying. She makes either $21 total or just below that amount.

Step-by-step explanation:

w is the box and when a number is beside a letter it is multiplication and then 9 dollars for trying. the < with the underline means that it is the same amount or less.

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
