(9) The highest point in Canada is Mount
Logan, which is in the 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?
To solve this problem you will have to make a ratio table (T chart).
One the right side with % the other with m.
Then divide under the T line write 100 on the left side and 3747 divide both by 100 and you get 1 for the percent and 37.47 on the other then times both by 159 and you got your answer
(5957.73)
(8) The original price of a jacket was \$84.00.
A store manager marked the price down
by 25.50%.
By how much was the price
reduced?
You draw a T chart and put % on the left side and \$ on the right side.
Then Under the T line on the left side write 100 on the right write 84. Divide both by one hundred after that times it both by 25.50 and you get the answer.
