If a bathtub is being filled at a rate of 2.5 gallons per minute, how long will it take to fill the bathtub?

You need say how big the bathtub it is or you cant do it.

type the rest and ill try to answer it

Let x = number of minutes

( 2.5 liters/min )*(x) = 30 liters

         x = (30 liters) / (2.5 liters/min)

         x = 30/2.5 min      [note how liters cancel]

         x = 12 min

Check:

 Is  2.5*12 = 30   ?

       30 = 30   ?yes

saving = more money

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.
