Question: Ed bought two teddy bears. The heights of the two teddy bears are 134 feet and 456 feet. Estimate the average height of the teddy bears.
A ) 4.5 feet
B ) 2.5 feet
C ) 5.5 feet
D ) 3.5 feet
Steps to derive
1 Total height = 134 + 456
[Round to the nearest half.]
2 ≈ 2 + 5 = 7
3 Average height = Total height of the teddy bearsNumber of teddy bears
[Substitute and simplify.]
4 = 72 = 3.5
5 The average height of the teddy bears is about 3.5 feet.
Hence the right answer is Option D
