Scribepost for February 2, 2010

Today in class, we had a couple of assignments to do. We had to fill in our foldables and do the odd questions in our textbook.
Here are questions 1 and 3.

#1:
Draw a diagram to show how you could represent the cost of a $100 item with and without tax.

The diagram I drew was a ratio table. With a ratio table, you would be able to see how much the item costs and how much you would pay with the tax.



#3:
Kyle says that a population increase
of 15% one year followed by an increase of 10% the next year is the same as a population increase of 25% over two years. Is Kyle correct? Explain your reasoning.

Kyle is incorrect. The population increasing by 15% and then by 10% would be a greater population than if it just increased by 25% altogether.

I got my answer using a ratio table:


Thanks for reading my scribe!! Please comment :)
