1.075 + 27.105= 0.401 + 9.28 =
33.1 + 1.95=
13.2 - 1.78=
3.11 - 0.376=
0.9 - 0.245=

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
