According to the Stack Overflow Developers Survey of 20182 , 15.6 percent of developers do not spend time outside. If we encounter 5 [randomly selected] developers in the cafeteria, what is the probability that exactly 2 of them do not spend time outside.

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
