Hannah's scribepost for February 3, 2010

question 6.

A store discounted items by 50% off the original price one week. The following week and additional 10% was taken off the already reduced price. The regular price of a CD player is $85.00. What is the reduced price in the second week?

First we find 50% of $85.00 and subtract it from the original price.

50% is 42.50. We take that away from the original price because it's the discount.

So the selling price for the first week is $42.50

$42.50 is now our new 100%. We now have to find 10% discount of that. Instead of finding 10% and subtracting it from the total, a shorter way is to just find 90%. Because 100% take away 10% equals 90%. Using this method, you will be able to skip one step which is subtracting. This will also save you time.

The selling price after the second week is $38.28

question 8.
Represent the percent on each statement on a hundred grid.
a) 79.1% of all the students are right handed.

b) The average person in Canada uses about 223% as much water per day as the average person in France.

c) The school enrollment increased by 0.8% this year.

question 9.

I'm sorry, it's late.

Wow hannah .
Your pictures of solving the questions worked out really well with your explanations , it was very understandable and organized. It will also be very helpful to people who mightve missed what we did, and for people that mightve gotten confused when we did it. So great job (:
