Opener (pdf).

Lesson (pdf).

1. Braingenie if you want more practice on Solving and Graphing Inequalites in One Variable.

2. By Friday: Create a blog post where you not only solve the following problem, but explain how you used Dimensional Analysis in order to solve it. Try to write this post as if you were explaining this process to someone who didn't know anything about Dimensional Analysis. They should be able to read your post and have a pretty decent understanding of how to approach a problem like this.

This blog post is due by first period on Friday, but I highly recommend you start on it tonight so that, if you have difficulties (either with the blogging or the concept of Dimensional Analysis), you can come in and get some help on Tuesday, Wednesday or Thursday.

Please title your post Today's Price of Gas in Australia. The problem I would like you to solve is to figure out what today's price of gas is in Australia, but in U.S. Dollars per Gallon. Australian gas, not surprisingly, is priced in Australian Cents per Liter, so you have some Dimensional Analysis work to do here. (Don't forget you practiced creating some Math Notation previously - you probably want to use those skills to help you illustrate this blog post.)

So you're trying to do this:

Here are two links that will help:

1) Currency Exchange Table (US Dollars to Australian Dollars)

2) Australian Fuel Watch (use the Metro Average for ULP - note that the number given is in Australian Cents per Liter)

As a learning bonus, if you are somewhat surprised by the answer you get (in US Dollars per gallon), talk to your social studies teacher (or your parents) about why there is such a difference between the price of gas in Australia and in the U.S.

As you write this post, please remember that your blog is public, and this is part of your Digital Footprint. How do you want to represent yourself to the world?
