Mai and Andre found an old, brass bottle that contained a magical genie. They freed the genie, and it offered them each a magical $1 coin as thanks. The magic coin turned into 2 coins on the first day.
The 2 coins turned into 4 coins on the second day.
The 4 coins turned into 8 coins, on the third day.
This doubling pattern continued for 28 days.
The number of coins Mai had on the 28th day is very, very large. Write an expression to represent this number without computing its value.

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

where is the figure
