Given: 
Find: 
Solution: The first step that we must take is to convert the tree height to centimeters and after doing so we would just subtract 70 cm from that to get the pole height.
<u>Convert to cm</u>
<u>Combine</u>
<u>Subtract 70 from the tree height</u>
Using the information from the problem the height of the pole would be 3955cm.
Answers are: 83 and 77
Notice how...
The jump from 98 to 97 is a decrease of 1
The jump from 97 to 95 is a decrease of 2
The jump from 95 to 92 is a decrease of 3
The jump from 92 to 88 is a decrease of 4
The pattern of decreases so far is: 1, 2, 3, 4
So the next decrease is 5
88-5 = 83
And the decrease after that is 6
83-6 = 77
