3(-2x - 1) = 2(x + 5)

Solve for X

3 ( -2x -1) = 2 ( x + 5)

-6x - 3 = 2x + 10

-6x - 2x = 10 + 3

-8x = 13

x = 13 /(-8)

x = (-13/8)

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
