Sales Tax

you have to find the:
The tax on the bicycle
&
What is the total price including tax
Our objective
- Both of us wanted to learn more because we kind of got confused with this lesson and we worked on it and we got it and now we want to show you guys how we got it.

- We mostly struggled on this lesson. We both would get confused on the mutiplying and adding and how to steps go...

Steps:
Step 1:
First get the main number (\$119.95) and the second number (0.06)
Step 2:
then you multiply both of them together
\$119.95
x 0.06
---------

= \$7.197
Step 3:
But to fing the initial price, we add.
\$119.95 (price) + \$7.20 (tax)
---> \$127.15 total
/ also means: \$7.20
