John's Scribe Post-Textbook 10, 13 and 14

10) When water freezes, its volume increases
by approximately 10%.
a) By how much does the volume of a) 10
-- = 0.1 0.1x750=75mL
750 mL of water increase when it 100
freezes?

b) What is the volume of ice created? b) 825mL


14) 4% of 100 is the same as 8% of what
number? Explain how you arrived at
your answer.

I arrive at 4% is half of 8% and 50 is half of 100

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? a) Commission is the portion of the sale price that the real estate agent earns.

b) If a house sells for $345 000, how
much commission does the real estate
agent make on the sale of the house? b) $18 700

Comment if I did something wrong.

  1. Hi John! You had a mistake on your answer. Its question 14. You didn't answer the question the answer is 200% because if you do 4x2=8% then 100x2=200%. Also you could have shown how you got the answer to your question. Other than that, you did a very good job in your scribe post.
    Here is a video that you could have alos added:
