Shannon wants to make a scale drawing of her car on a 5 inch by 7 inch index card. Her car is 12 feet long.
She decided to use a scale of 1 inch : 0.5 feet. Would her drawing fit on the index card? Explain.

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
