A roller coaster at an amusement park rises to a height of 196 feet above the ground. So far, it has risen 36% of this height. To estimate the height the roller coaster has risen so far, Jake did the following.
1. Rounded 36% to 40%
2. Rounded 196 to 200
3. 10% of 200 is 20
4. mc003-1.jpg
5. 36% of 196 is about 80
However, Jake’s estimate was too high by almost 10 feet. Why was his estimate off by so much?

Answer:
Option 5 ; 36% of 196 is about 80
Explanation
Jake did some wrong calculations while estimating the height of roller coaster.
If we look at options one by one;
Option 1 :
36% of 196 is actually 70.5 while 40% of 196 is 78 so difference is 8.
Option 2 :
When rounded to 200, 36% of 200 will be 72
Option 3 :
10% of 200 is 20, this is far from the estimate
Option 5;
36% of 196 is about 80 whereas in actual 36% of 196 is 70. This difference between actual and Jake estimate is almost 10
