Preparing for Your Final

The time has come! The semester is almost over and you will be test free for a few weeks! The final will include the following concepts: Fraction Decimal and Percent Conversions, the Percent Bar Model, The Proportions Model, Discounts, Tax, and Tip. I know it seems like a lot, but you can do it! Below is an example of each type of problem. If you can see an area of confusion, come see me!

Tip

You will use the same steps as with tax. It is a percent of increase, so you set up the proportion the same way then add it to the original price.
