We have been given that The Walden University had 47,456 students in 2010, while Kaplan university had 77,966 students. We are required to compare the number of students in each of these universities in different ways.
(A) Let us first find difference between the number of students between the two universities. The difference between the number of students for two universities is 30510.
Let us now find what percentage is 30510 of 47456.

Therefore, Kaplan’s enrollment was 64.29% larger than Walden’s
(B) In order to answer this part, we need to find what percentage is 30510 of 77966.

Hence, Walden’s enrollment was 39.13% smaller than Kaplan’s.
(C) In this part we need to figure out what percentage is 47456 of 77966.

Thus, Walden’s enrollment was 60.87% of Kaplan’s.
Note: Please round your answers to required number of decimal values.
By finding the scale factor, we will see that the volume of the smaller solid is 86.75 m³.
<h3>
How to get the volume of the smaller solid?</h3>
If the solids are similar, then there is a scale factor between the two. Then the relation between the areas is equal to the scale factor squared, and the relation between the volumes is equal to the scale factor cubed.
This means that if the areas are 169 m² and 81 m², then we can write:
169 m² = (k²)*81 m²
Solving for k, we get:
k = √(169 m²/81 m²) = 1.44
Then if the volume of the large solid is 124.92m³ we can write:
124.92m³ = k³*V
Replacing k and solving for V we get:
124.92m³ = (1.44)³*V
(124.92m³/ (1.44)³) = V = 86.75 m³

I believe it would be A - 20% of the customers who ordered an appetizer did not order dessert.
The answer would be 6.4 I believe.
