These are similar to the Coin Problems, but are chart should
only have two columns, Now and Then. Your Equation will
usually come out of One of the Then cells. Add or subtract years
depending on if Then is the future or the past. In the second sentence
they usually also give you another comparison, like twice the age.
Put an equal after the first change, (+ or - years) and the new comparison.

the sample problems.

Intro Algebra continued

Intro to Algebra

We will now start learning about Algebra.
Algebra can be thought of as looking for
unknown numbers (sometimes called variables).
The unknown numbers are usually written as
a letter. The letter stands for a number we are
looking for. So for example 3+x=5 means
we are looking for the number that would
make the equation true. so we know that
2 = x would make it true. Let's watch a video
that introduces how we solve more questions like
this. https://youtu.be/rBf1eYwwQFE

Creating a Budget

Use Excel (or Google Docs Spreadsheet) to create a expense budget for a trip to Medice Hat.

Remember that you must start calculations in excel with the = sign.

Here are the information sheet and an example of how you should set up your Spread Sheet.

For more information on entering calculations into Excel watch the following tutorial.

Elections Math

We are going to look at the results of the last three elections and compare "Popular Vote" (percentage of the voters that voted for each party) to the proportion of the seats each party won in the House of
Commons.

Find the number of eligable voters in this election, as well as in the 2008 and 2011 elections. Then find out how many people actually voted in each election. What % of people voted? What percentage of these voters voted for each party? How many seats were there available in the House of Commons in each election? How many seats did each of the top 5 parties win? What percentage of seats did they win? Why is there a difference between this percentage and the Popular vote?

 

 

Most of this information can be found at election.ca including past elections (under the Main Website tab)

Scale Homework

Find a candy wrapper (or the label of some package),
draw a rough diagram of the cover and measure the original.
Choose a scale factor larger than one, but not so big that the
copy will not fit on one sheet of graph paper. Reproduce the
main components of the label (logos, drawings, large text, etc.).
Include the wrapper and your acle factor along with the calculations.

Coin Problems (Homework)

Complete the following (started in Class)


1. Sue had three times as many nickels as dimes.
If the total value of hercoins was $1,
how many of each kind of coin did she have?

2. You have a bunch of change in your pocket that
consists of only nickelsand dimes. If you have ten
less nickels than three times the amount of dimes,
and the total value of all of your change is $5.00,
how many of each type of coin do you have?

3. Margo had 7 more than two times as many
quarters as dimes. If the total value of
her coins was $10.15, how many of each
kind of coin did she have?

4. Josiah had three less than twice as many
nickels as dimes. If the total value of his
coins was $1.45, how many of each kind of
coin did he have?

5. A piggy bank contained $14.55 in quarters,
dimes, and nickels. If there were three more than
twice as many dimes as nickels and three less
than three times as many quarters as nickels,
how many of each kind of coin was in the
piggy bank?

6. Larry received $6.10 in tips one afternoon.
All of his tips were in quarters, dimes, and nickels.
There were five less dimes than quarters and seven less
nickels than dimes. How many of each type of
coin was there?

7. Vera's piggy bank contained $9.35 in quarters,
dimes, and nickels. There were six more than two
times as many nickels as quarters and four less dimes
than quarters. How many of each kind of coin was
there in the piggy bank?

8. A polka-dot change purse contained $12.25 in
quarters, dimes, and nickels. If there were five more
than twice as many dimes as nickels and one less than three
times as many quarters as nickels, how many of each
kind of coin was in the purse?

9. A collection of ancient coins contained old nickels,
dimes, and quarters. There were seven more than three
times as many quarters as dimes and sixteen less
than twice as many nickels as quarters. If the face
value of the entire collection was $38.45,
how many of each kind of coin was there?
