Problem
A sign at the fish market says, "50% off, today only: half-pound packages for just $3 per package." What is the regular price for a full pound of fish, in dollars?
Solution
The 50% off price of half a pound of fish is $3, so the 100%, or the regular price, of a half pound of fish is $6. Consequently, if half a pound of fish costs $6, then a whole pound of fish is dollars.
Solution 2
Let's say that a full pound at normal price costs dollars. Then, we can say that with the 50% off deal, the full pound would cost dollars.
