One two three can anyone able to helps me

Explanation below

Step-by-step explanation:

Plug in the x-value into the equation. Then evaluate/solve.

x=1        y=-8(1)+10     y= 2

x=2       y=-8(2)+10    y=-6

x=3       y=-8(3)+10    y=-14

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
