E. 35/4

Step-by-step explanation:

Multiply denominator (4) to the whole number (8) then add to the numerator (3)

(8× 4 + 3)/ 4

(32 + 3)/4

35/4

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
