Kara started a weight loss program weighing in at 250 lbs. after the first month, she lost 50 lbs. what percent of her weight did she lose?

250 lbs > 200 lbs

          -50 lbs

50/250 = 1/5 = 20%

20%

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
