Two different bacteria colonies begin with the same number of bacteria. The colony populations, P, and P2, are modeled by the equations Py = 100(2) and P2 = 100(5)' where is the time in hours.
Which describes the relationship between P, and P2 after 3 hours?

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
