Harry is building a model car. the actual car has a length of 15 feet and tires with a radius of 24 inches. his model car has a length of 1.25 feet. in order to create an accurate model, the radius of the tires on his model car should be

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
