N = 3st^4- 5sv solve for v

v = (N - 3st⁴) / -5s

Step-by-step explanation:

N = 3st⁴- 5sv

N - 3st⁴ = -5sv

(N - 3st⁴) / -5s = v

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
