The faa now figures the average checked bag to weigh 11 pounds. this is up from previous figure of 10 pounds. find the amount of increase

-- The amount of increase is (new value) - (old value)

(11 pounds) - (10 pounds)  =  1 pound .

-- The fraction of increase is (amount of change) / (old value)

(1 pound) / (10 pounds)  =  1/10  or 10%

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
