Sue problem

This is the most popular problem in class but is a good example of problems where you need to choose the information. So here we go:

Sue bought a teddy bear, a yo-yo and a puzzle. She paid $ 45.90 including the tax of $10.23. How much change should Sue receive if she gave the clerk $60?

First of all, we need to decide which numbers in the problem are going to help us to find the solution.

It´s important to notice that the tax is already included in the 45.90, so you do not have to add it to the total. It can be said that the value of the tax is just information.

Another important thing about the problem is the use of cents. For example 45. 90 means 45 dollar and 90 cent. So 60 is 60 dollar and 0 cents.

Finally , in order to find he change we need to substract 60.00 and 45.90
