A 45-gallon tank is filled with water, and then water begins draining from the tank at a constant rate of 1.5 gallons per minute.
Let t represent the number of minutes since the tank started draining.
Let v represent the number of gallons of water in the tank.
Write a formula expressing v in terms of t.

v is a function of t, and we will call this function f (so that f(t)=v). Write a formula for f.

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
