Answer 2

2.33⋅10^4

Explanation:

From the table, we know that in 1900, 3.7⋅10^3 students were enrolled, and in 1950, 2.7⋅10^4 students were enrolled.

In order to answer "How many more students were enrolled at the University of Michigan in 1950 than in 1900? " we have to subtract this numbers, as follows:

2.7⋅10^4 is equivalent to 27000

3.7⋅10^3 is equivalent to 3700

27000

-

3700

----------

23300, which is equivalent to:

23300 ⋅ 10000/10000 = 2.33 ⋅ 10000 = 2.33⋅10^4
