The quantity a varies directly with b and c and inversely with
d. the quantity d is tripled. which of the following must be true for the relationship to remain the same?
both c and b must be tripled.
the product of c and b must be tripled.
both c and b must be multiplied by 1/3.
the product of c and b must be multiplied by 1/3.

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
