Asporting goods store offers a 40% discount on all golf clubs. rocco spent 20% of the money in his savings account on a golf putter. he paid $48 for the putter after the discount. how much money did rocco have in his savings account before buying the putter?

Here is what we know. We know that 20% of the money in his savings account was spent on the putter. 20% is 1/5. So in this case all we need to to is take the $48 and multiply that by 5. 48 times 5 is 240. This means that Rocco had $240 in his savings account before he bought the putter. 

Hope this helps.
