Demvry's Math Book H.W

Page's 42-43

5) The commission for the sale of a house was 63/4%. If the house sold for $345 000, how much was the commission? Show your thinking.



I divided 100 by 100 and got 1 and then I times it with 6.75 which then I ended up with 6.75%
I did the same steps as the percent as in dividing 345 000 by 100 and it got me 3450 which then I times it with 6.75 leading me to $23287.50
Sorry if it made no sense!



6) Table salt is a chemical compound of sodium and chlorine. Recommended daily intake is about
1700 mg. If Canadians consume 182% of this amount on average, how much sodium is one person eating daily?




I divided the 100% by 100 and ended up with 1%. I times that 1% by 182 and ended up with 182%.
I did the same steps as the percent and ended up with 3094 mg.
Sorry if it didn't make sense again!
