The gas tank is 20% full. at $3.00 per gallon of gas, find the cost to fill the tank. (1 gal = 231 in.3) at $3.00 per gallon of gas, it will cost $ to fill the tank. the gas tank is 1.25x1.75x11

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
