Isabel's Textbook Scribe Post ( 3, 9, 13 )

*Guys! Sorry that this post is late but I hope that this scribe will help you :)*

5. Determine the percent of each number. Give your answer to the nearest hundredth:

• A. 2/5% of 325 is 1.3 but if you estimate it you will get 1. This is how I got the answer:
Divide 100/5 to get 20
Divide 325/5 to get 65
Multiply 20x2 to get 40
Multiply 65x2 to get 130
Divide 40/100 to get 0.4
Divide 130/100 to get 1.3

Another one is by finding the decimal:

Divide 2/5% to get 0.4%. Make 0.4 out of 100. Divide 0.4 and 100 by 100 and you'll get 0.004/1. The last part is where you multiply 0.004 x 325 to get 1.3.

• B. 15 1/4% of 950 is 144.875 but if you estimate it you will get 144.88. This is how I got the answer:
Divide 100/10 to get 10
Divide 950/10 to get 95
Divide 10/2 to get 5
Divide 95/2 to get 47.5
Divide 5/5 to get 1
Divide 47.5/5 to get 9.5
Divide 1/4 to get 0.25
Divide 9.5/4 to get 144.875

Another way is by finding the decimal:

Divide 15 1/4% and you'll get 15.25. Make 15.25 out if 100. Divide 15.25 and 100 by 100 and you'll get 0.1525/1. The last part is where you have to multiply 0.1525 x 950 to get 144.875.

• C. 175% of \$125.50 is \$219.65 but if you estimate it you will get \$219.70. This is how I got my answer:
Divide 100/2 to get 50
Divide \$125.50/2 to get \$62.75
Divide 50/2 to get 25
Divide \$62.75/2 to get 31.375

Another way is by finding the answer by decimal:

Divide 175 and 100 by 100 and you'll get 1.75/1. You now multiply 1.75 x \$125.50 to get \$219.625

9. The highest point in Canada is Mount Logan, which is in Yukon Territory. Mount Logan is 159% as high as the highest point in Alberta, Mount Columbia. The elevation of Mount Columbia is 3747 m. What is the elevation of Mount Logan?

Divide 159 and 100 by 100 and you'll get 1.59/1. You now multiply 1.59 x 3747 and you'll get 5957.73 m.

13. Suppose a real estate agent receives 5% commission on the first \$200 000 of a house's selling price, and 6% on the remaining amount.
• A. What does commission mean?
When I googled the meaning of commission it says: a fee charged by an agent for his/her service in facilitating a transaction, such as buying or selling of securities or real estate. So then, it is a fee that house realtor gets when he/she sold a house.
• B. If a house sells for \$345 000, how much commission does the real estate agent make on sale of the house?
How did I get 145 000? I subtract 345 000 to 200 000 and got 145 000.
To get 6% of the 145 000 you have to first- Divide 100/10 to get 10. Divide the 10/10 to get 1. Multiply the 1x6 to get 6. Divide 145 000/10 to get 14 500. Divide 14 500/10 to get 1450. Multiply 1450x6 to get 8700.

To get 5% from the 200 000 you have to first- Divide 100/10 to get 10. Divide 10/2 to get 5. Divide 200 000/10 to get 20 000. Divide 20 000/2 to get 10 000.

You then have to add 8700+10 000 which is equal to 18 700.

1. Hi Isabel I really like your scribe post. but then you should add color and make the font bigger so that I can see it more clearly. ok. So your scribe post is really long at that means you worked really hard. I like the video even thought its short it still helps me a lot. I can see on number 5 you did 2 explanations and that's great. It's also great because you showed the other way the way Mr.Harbeck told us today.
It's great that you made the question bold. For 13 should should have separate the papers a little because it looks confusing a bit. I like how that you made your pictures instead of getting it from Google. Your link was great too.
GOOD JOB ISABEL :)

2. Good Job Isabel,
You had a great post. There was lots of information, pictures, and a good video. You could have made this scribe post better by adding colour and other extra stuff to make important information pop out and to make it look interesting.
