Example Question #6 : Solve Multi Step Problems With Positive And Negative Rational Numbers: Ccss.Math.Content.7.Ee.B.3
If a server at a restaurant gets a tip on a bill of , then what will be the amount of the tip?
The first step to solving this problem is determining what operation we are going to use.
Think:we know that the tip is going to be of . The keyword "of" gives us a clue and indicates that we are going to multiply.
As we have learned in previous lessons, we need to convert our percentage into a decimal before we are able to multiply:
Next, we can perform the multiplication operation and find the tip:
The server's tip will be
