Ryan's Scribe Post
This scribe post is about 3 questions on pages 142 and 143.
7. Two hundred tickets are being sold for a school draw.
a) What is your chance of winning with one ticket? Express your answer as a percent.
Your chance of winning with one ticket would be 0.5% because lets say 200 tickets is 100 tickets then your chance of winning with one ticket would be 1%.
b) How many tickets would you need to purchase to have a 2.5% chance of winning?
You would but 5 tickets because if 1 ticket is 0.5% then if you buy 4 more it would equal 2.5%
13. Suppose a real estate agent receives 5% commission on the fi rst $200 000 of a house’s selling price, and 6% on the remaining amount.
a) What does commission mean?
Commission means a part of the sale price that the real estate agent would earn.
b) If a house sells for $345 000, how much commission does the real estate agent make on the sale of the house?
The agent would make $18 700 on the house.
16. Josephine scored 12 baskets out of 30 shots in her first basketball game this year. Her scoring average was then 40%. The next game, she made ten shots and raised her scoring average for both games to 50%. How many of the ten shots in the second game were baskets?

Summers textbook awnsers
(textbook answers 3, 7, 11, 13)
For number three i got:
I think that Shindi meant that if the part that your not counting in the percentage is shaded it would be easier to figure out the percentage.
Here are my guesses to the ones i think are easier with coloring in the non percentage part.
1. 60%

2. 10%

3. 20%

Those are some examples of ones that would be easier to read if the other part was highlighted.
For number seven i got:
A)attendance- 3.2%

B) Singapore cat:Siberian tiger-0.13%

C) Yukon river: Frasier river-230%



For eleven i got:
1) Alberta-113%


2) Saskatchewan-100%

For number thirteen i got:
A) To convert 1/3 to a fraction the equation would be 1 divided by 3=0.3333333333333.
1/3 can be shown on a hundred chart by dividing one square into three pieces and coloring in one.

B) Sometimes repeating decimals are harder to show on a hundred chart because you have to convert it.
Sorry about the video it wouldn't load.
