2. Convert 21/300 to a percent.

7

Step-by-step explanation:

21: 300*100 =

(21*100): 300 =

2100: 300 = 7

21/300 = x/ 100

2100/300x = \^o^/ 7

       ^

 (division)

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
