Question

There were 35 gallons of water in a tank and 4.5 gallons of water in a pail. An equal amount of water was poured into the tank and the pail. The ratio of the water in the tank to that pail became 7:2.

a. how much water was in the pail at the end?
b.how much water was poured into the pail?

Answer 1

If x gallons were poured, then

(35+x)/(4.5+x) = 7/2
x = 7.7

Now it's easy peasy.

Answer 2

No dude, can you explain how to get 7.7?

Answer 3

I am afraid that unless you post HOW you receive the answer, your equation really does not help. Unless you mean to say that you would do 35+4.5+2x=3.5 That may make sense, though I am not sure. I will have to check

Answer 4

Oh Wow I am terribly sorry. I just realized how easy that is... Thank you so much!

Answer 5

I believe that the answer is actually 7.8 gallons. Let me explain. The x-x cancels out, leaving it as 35/4.5 Dividing that gives you 7.8 gallons.
