A woman is trapped in a room at the center of a maze. The room has three exits. Exit 1 leads outside the maze after 3 minutes, on average. Exit 2 will bring her back to the same room after 5 minutes. Exit 3 will bring her back to the same room after 7 minutes. Assume that every time she makes a choice, she is equally likely to choose any exit. What is the expected time taken by her to leave the maze

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

35-60 students are taking math.

d 600 because 15*10*2=300

300+300=600
