In Bobs cooler there are 7 bottles of soda and 9 bottles of water. Bob is going to choose 7 bottles at a random from the cooler to give to his friends. What is the probability that he will choose 4 sodas and 3 waters?

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
