Today we talked about the Golden Ratio. We talked about how are body and alot of other things will work this way.For example If you measure your arm, and then your elbow and down and you divide the long ways by the short way you will get the number 1.618 (That is the Golden Ratio) and if it`s not 1.618 it will be very close.

After we talked about that we went to a question about sales and rate savings.Here's an example.

Corey buys a jacket on sale for $53.99. Before the sale the jacket cost $63.89. What is her percent rate of savings?
1. First you have to divide the sale price by the original price.
sale price/original price = $53.99/$63.89 = 0.8450
2. Then you round it off.
0.8450 rounded off to 0.85 = 85%
3. Then minus the percent from 100% and you find the rate of savings
85% - 100% = 15%

Corey got a 15% rate of savings.

Here is another example of something we did....

new/old

1 Shirt $16.99/$18.99 = 89% 89% - 100% = 11% off
2 Pairs of socks $2.67/$3.29 = 81% 81% - 100% = 19% off
1 Sweater $19.99/$25.50 = 78% 78% - 100% = 22% off

After That we has to find out how much the tax would be for all of these items in total.

$16.99 + $2.67 + $2.67 + $19.99 = $42.32 - total items
GST - 0.06 x $42.32 = $2.54
PST - 0.07 x $42.32 = $2.96
$42.32 + $2.54 +$2.96 = $47.82 - total incl. taxes**

We also talked about ratio's and how they could compare a part:part or a part:whole
