problem 3.3 and how to figure out the tax of an item

Today in class, we were working on problem 3.3. It focused on taxed items and how to find the tax of an item that can be purchaced. For example, if you bought 3 shirts for $9.99, you bought 2 pairs of pants for $20 , and the tax was 7% how would you find the total price.

1. First, you do $9.99 + $20= 29.99

2. Then you do $29.99 * .07 (because its 7 percent tax)=$ 2.0993 (which is about $2.1)

3. Then you take $ 29.99 + $2.1= $32.09

So, in conclusion $32.09 would be your total =]

Thats how you figure out how to add the tax to the amount to get the total
