Plant a si 18 inches tal after one week, 36 inches tal after two weeks, 56 inches tall after three weeks. plant b si 18 inches tall after one week,36 inches tall after two weeks,54 inches tall after three weeks. which situation represents proportional relationship between the plants height and number of weeks?

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
