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. 20 (4) = 80
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?
A. He made a computation error.
B. He rounded the percent up to 40% and the number up to 200.
C. He made a rounding error, and should have rounded 196 down to 100.
D. He should have rounded the percent down to 30% and the number down to 190.
